Gooch & Housego Instruments: IEC 62471 Photobiological Hazard Measurements

The lighting industry is much different today than it was just a few years ago. With new types of lighting being released all the time, it’s important that all of these new lighting sources are properly regulated.

Important IEC 62471 Standards

The government enacted tough lighting standards to help evaluate and control the optical radiation hazards from lamps at all points of human access through a standardization of measurement techniques. These standards deal with spectroradiometric measurements of extended light sources, as opposed to point sources, in terms of radiance and irradiance. These sources can be altered by filtration, projection, and diffusing options in terms of distribution and spectral content. The International Electrotechnical Commission standards also take into account retinal hazard, distance, projected size, and response.

Manufacturers Required to Meet IEC Standards

All manufacturers of lighting sources are required to measure the amount of light produced and evaluate human hazards in accordance with the latest IEC standards.

LED Uses Becoming More Diversified

With the decrease in cost, LED lighting is being used for much more than just cheap, environmentally-friendly lighting. Analysts are expecting LED lighting uses and applications to see a big jump through the use of UV LED technology. LED testing leaders, Gooch & Housego, explain UV LED technology and what it means for the industry.

Uses for UV LED Technology

The potential uses for UV LED technology are almost endless. Analysts are seeing immediate applications in purification and disinfection by 2017. The traditional UV lamp business is slowly being replaced by UV LED technology, which is much cheaper and less intrusive on the environment.

New Technology Growing at a Rapid Clip

According to researchers, the growth of the UV LED market in UV curing has been nothing short of astounding. In 2008, the market was only around $20 million, but grew to around $90 million in 2014, which is a compounded yearly growth rate of over 28%. Analysts predict that as UV LED technology is used for other applications like purification and disinfection that the market will grow to at least $500 million by 2019.

These LED Applications are Only the Start

Researchers point out that if LED lighting continues to take over other industries, including horticultural lighting, general lighting, biomedical devices, and other applications, the growth of the industry will grow much larger than these initial estimates. LED lighting is no doubt a complete game changer in the lighting industry, and big name manufacturers are scrambling to produce as much of this type of lighting technology as possible to meet the growing demands.

Some Waterparks are Stepping up Their Game with LEDs

Waterparks around the world are always looking for bigger and better ways to appeal to thrill seekers. While waterparks have attempted to create larger waterslides to cater to park attendees, few parks have used technology to help provide their guests an experience like nothing ever seen before. Gooch & Housego, leaders in LED testing, explains how these parks are incorporating LED lighting in their attractions.

German Park Using LED Lighting to Improve Experience

An indoor pool facility on the German coast of Bremerhaven is taking the idea of a waterslide to a whole new level through the use of LED lighting. This new LED slide allows participants to feel as if they are traveling through a wormhole full of multicolor rings, powered by a whole host of LED lights. While the waterslide looks completely normal from the outside, once inside sliders quickly realize that this is unlike any slide in the area. The slide is 25 feet tall and 256 feet in length which gives thrill seekers plenty of time to enjoy this unbelievable LED light show.

Waterpark Features Multiple LED Lighting Effects

Thanks to cutting edge LED technology, waterpark officials can display a variety of different lighting effects, including multicolored rings as well as a starry sky just before the sun begins to rise. With this technology, waterpark attendees will be excited to jump in the slide to see what sort of LED light show is being displayed at the time.

Laser Stimulation Reveals New Details in Fossils

Researchers in Kansas are discovering that lasers are offering fossil details previous unseen with traditional UV light.  Paleontologists are extremely excited about these new findings as they could help identify fossils in soil more quickly and possibly even detect fake fossils. Gooch & Housego, the leader in light metrology, laser optics and spectral imaging devices, explains:

  • Lasers First Used to Examine a Microraptor From China: Researchers initially used lasers several years ago when examining a microraptor from China. During their research, they actually found a secondary fossil in the material surrounding the microraptor. Once this second fossil was found, it was sent to Thomas Kaye with the Burke Museum who actually pioneered this laser technique.
  • Technology Hhs Improved Since Original Usage: Since the initial use of lasers, researchers have fine-tuned their techniques to be more effective. Laser technology has become cheaper as of late allowing researchers to purchase short wavelength lasers on Internet sites like eBay to experiment with. By using digital photography equipment, researchers have developed a variety of techniques to reveal intricate details from fossils that would be impossible using traditional UV light.
  • Lasers can Also Detect Fakes: One of the largest benefits of using lasers in fossil identification is the ability to detect fakes. Museums are always looking for the next huge fossil find, which has created a market for extremely detailed fraudulent fossils.  These fraudulent fossils may be completely fake or a combination of fossils from different places brought together to look real. Previously, these fakes were extremely hard to identify, yet with lasers, museums are more easily able to spot fraudulent fossils.

Gooch & Housego Offers a Variety of Spectral Imaging Devices

Much like lasers, hyperspectral imaging devices allow light to be divided into many bands, which can be extended far beyond what is visible to the human eye. For more information on our spectral imaging devices, like our popular HSi-440C, contact us today toll free at 800-899-3171.

The Skin from a Squid Furthers IR Technology

“Look deep into nature, and then you will understand everything better.” – Albert Einstein

Scientists from the University of California, Irvine have recently found that this quote from Albert Einstein rings true when it comes to squid skin. These researchers recently discovered that squid skin can be adapted to create a form of IR camouflage for soldiers. Optical radiation, light measurement and imaging experts, Gooch & Housego, explains:

  • Researchers Have Developed a Film to Reflect Infrared Light: Scientists have developed a type of sticky film that, when stretched, offers a level of IR camouflage to avoid detection from thermal cameras.
  • Help for Our Soliders: In the past, soldiers have worn brown and green camouflage uniforms to blend into with their surroundings during the day. While this works well in foliage during the day, these uniforms leave soldiers vulnerable to detection in low light or night situations. Researchers developed stickers that can be used in these situations to match a soldier’s infrared reflectance to the background, which helps to prevent detection.
  • Squid Skin Explained: Squid skin uses cells that are known as iridocytes that contain a protein called reflectin. Squids then are able to change the thickness and spacing of these layers of proteins to alter how the cells can reflect light.
  • Researchers Focused on Inexpensive Solution to Problem: Researchers have found that the most inexpensive way to utilize this technology is to create a disposable type of adhesive that can easily stick to and be removed from uniforms.  This way soldiers could quickly apply the tape to avoid detection and then dispose of it shortly thereafter.

Gooch & Housego IR Detection Products Help Determine IR Levels

At Gooch & Housego, we manufacture a variety of IR detection equipment, including the spectroradiometers 770-NIR and 750-NVG which make IR detection a snap. For more information on our suite of products, contact us today toll free at 800-899-3171.

Could LEDs Help Our War Vets?

Researchers in Boston are extremely excited about findings they’ve seen in a pilot program using LED treatments to improve brain function for veterans suffering from what has come to be known as Gulf War Syndrome. Gooch & Housego actually offers spectroradiometers that could be used in testing the LEDs for this type of therapy.

  • What is Gulf War Syndrome? The U.S. government defines Gulf War Syndrome as a variety of unexplained chronic medical conditions, including headaches, joint pain, fatigue, dizziness, memory problems, insomnia, respiratory issues, and indigestion.
  • How Will the LED Treatments Work? Veterans in the study will wear a helmet that is lined with LEDs that deliver red and near-infrared LED light to the scalp along with nostril diodes that deliver additional light deeper into the brain. The entire treatment is painless and lasts about 30 minutes.
  • The Clinical Trial: There is a clinical trial currently underway that will work with 160 Gulf War veterans. Half of those in the study will receive the actual treatment, while the other half will receive a placebo using fake lights. The veterans will switch so that everyone is exposed at some point to the treatment, but they will not know when they received it.
  • This Technology Isn’t New: This same technology has actually been used for years to treat muscle pains and aches, as well as to help wounds heal faster. Researchers are now beginning to use the same technology to hopefully improve brain function. MRI scans have shown that LED therapy helps to increase blood flow in the brain and may actually have an effect on already damaged brain cells. It is thought that brain damage from explosions or exposure to certain chemicals may be able to be helped with this type of LED therapy.

Effective LED Testing Key in This Study

As is often the case, LED testing will be key to determining the validity of this study. Using spectroradiometers, like our OL 770-LED, means that researchers should be able to accurately determine whether LED therapy is effective against Gulf War Syndrome.

LED to be the Exclusive Lighting Aboard the Chinese Space Station

China is working diligently on a space station known as Tiangong programme, which is slated to be completed in 2022. One of the recent announcements revolving around the technology of this space station is that it will be using LED lighting exclusively.This includes a variety of LED lighting, including spotlights for missions and docking, as well as lighting used inside the space station for tasks such as reading lamps for the astronauts. LED lighting is extremely small, lightweight, and energy efficient making it a great option for China’s new space station.

China has Been Using LED Lighting for Quite Some Time

This is not the first application of LED lighting for the Chinese space program. In fact, China used LEDs on the Shenzhou 7 spacecraft in 2008. This was the spacecraft that sent 3 astronauts into space for the country’s first spacewalk.

Benefits of LED Lighting in Space

There are a whole host of benefits of LED lighting being used in space. When conventional lighting is used in space, it requires pressurized gases with a high voltage current, while LED lighting does not. Without these pressurized gases, it is much safer to use LED lighting while in space to prevent potential issues with high voltage current. The China space program began to look at LED lighting in 2003, but did not think the technology had advanced enough to be useful until 2008. In testing, Chinese scientists used spectroradiometers to ensure that the LEDs would remain reliable and stable, even while being exposed to radiation as well as extreme hot and cold temperatures, which are commonplace in space.

Gooch & Housego OL 770 Spectroradiometer

Just as was the case with China space travel, spectroradiometers are extremely beneficial for LED testing and measurement gathering. The OL-770-LED test and measurement system is a high-speed system that can be customized to a variety of applications.

  • New MTC Offers Whole Host of Uses: The new MTC is so small that it can easily fit inside a smartphone, which opens up huge opportunities for applications in areas such as home maintenance, energy efficiency, personal safety, mechanical repairs, and more.
  • Many Challenges in Bringing MTC to Market: In the development of the MTC, FLIR had to overcome a variety of challenges. The company wanted to ensure that the thermal camera was small enough to be used with mobile phones, which brought up a whole host of difficulties. The size of the MTC measures only 10mm high, consumes less than 150 mW of power and a weight only .55g. This combination allows the device to be run by standard mobile phones.

The first product that FLIR developed was for the iPhone that helps to create a thermal camera system, complete with a free app to control the camera. This allows users to capture both video and still thermal images, as well as a temperature sensor for spot readings.

It remains to be seen how various industries will use micro thermal imaging technology, but as the price continues to drop, industries are bound to take notice and begin to use this type of technology in all sorts of applications.

At Gooch & Housego, we are continually amazed with the technology advances in the thermal imaging industry. One challenge when using thermal imagers is accurately assessing the spectral response of your thermal imaging sensor. In regards to imaging detector spectral response, Gooch & Housego has developed the OL 750, which makes this process incredibly easy. Contact us today at (407) 422-1371 to learn more about how the OL 750 can help assess the accuracy of thermal imagers.

SPIE Calling for Input from Photonics Industry on new ITAR Rules

Starting May 5th, a comment period of 60 days is being introduced to allow photonics companies to offer input regarding controlling the export of various photonics and optics technologies. The export of these technologies is regulated through Category XII of the US Munitions List, which is overseen by the International Traffic in Arms Regulations (ITAR).

The International Society for optics and photonics, SPIE, is concerned that the current proposal could be detrimental for US companies. A SPIE official was quoted as saying the proposal has “broad implications for the US optics and photonics industry both now and into the future.” Gooch and Housego’s Sr. Vice President of Life Sciences & Instrumentation Alex Fong says that “This is a critical opportunity to ensure both competitiveness and growth for the industry.”

Industry veterans worry that the current, as well as any subsequent additions to the regulations, are stifling global competitiveness. SPIE  hosted a webinar on May 12 for companies in the photonic and optics communities so they could voice concerns and understand the implications of additional regulations under ITAR. Companies have until July 6th to make comments on the proposed new Category XII rules, which ultimately govern ITAR.

The economic impact of further regulation could have a lasting effect on US based companies.  Currently, companies based abroad are able to sell freely and are then able to generate and invest profits back into businesses to further fuel innovation. If US-based companies are forced to adhere to additional regulations, officials with SPIE and other lobbying groups are worried that non-US companies may outpace the growth of American companies in these sectors. It is important for US companies in this industry to ensure their voices are heard prior to the July 6th deadline.

Could Coal be Replaced as the Energy Supplier of America One Day?

Across the country, energy companies are turning away from coal, and towards natural gas and solar power as ways to generate energy more efficiently, while being much safer for the environment.

In 2014, PV or solar-powered energy accounted for .5% of the country’s electricity, while natural gas accounted for a respectable 27%, according to the US Energy Information Administration. While the energy produced from PV may seem like a minuscule amount with the costs of solar and natural gas plummeting, it’s no question that more companies will be moving away from coal and towards these greener alternatives.

Solar Industry is Booming

According to the EIA, there was an increase of 100% in PV generation from 2013 to 2014.  This represented the largest growth rate for any energy source in the time period–more than natural gas, as well as wind.

Big Business Getting Behind Solar Energy

Companies around the country are beginning to take notice of the benefits both, from a public relations standpoint, as well as cost savings that can be seen by utilizing solar technology. Apple recently announced that they are investing in an $800+ million farm that will power their California facilities. Other companies, such as Walmart and Starwood Hotels, are also looking to use solar panels to power their operations around the country and ultimately, around the world.

One of the driving forces behind solar growth has been tax credits. Companies are seeing that they can save significant money in not only energy costs, but also in tax liabilities through utilizing solar energy. Hopefully government agencies will continue to offer these tax credits, which have undoubtedly had a huge effect on the growth of renewable energy sources. With some of these tax credits set to expire soon, renewing this legislation should be high on the to-do list of every politician.

Use Gooch & Housego’s OL750 to Measure PV Efficiency

One of the difficulties when utilizing solar energy is determining PV efficiency. Gooch & Housego has solved this problem by creating the OL750 spectroradiometer, which can easily measure the PV efficiency of your solar cells. As more companies turn to solar power for energy generation, it will become even more important to ensure that solar facilities are performing efficiently.
