It can be used in both the visible and infrared light spectrums, making the evidence-gathering process more efficient and accurate.
As part of our continuing efforts to push photovoltaic science forward, we've learned how to get sensitivity outside the visible light spectrum, including the infrared, with our polymers," said Russell Gaudiana, Ph.
The researchers used a combination of red, blue, green and white LEDs in order to produce the full light spectrum.
The HL-85-3W-UV365 Ultra-Violet LED Spotlight from Magnalight produces an ultra-violet light beam in the 365 nanometer end of the light spectrum, making it ideal for law enforcement and investigative applications that require an effective UV light source for revealing hidden details and luminescent compounds.
The final OLED casts a colour of light very near to warm white point A, a standard measure of the white light spectrum reached by some incandescent bulbs.

The new imagers use a back-illumination technology to boost QE (quantum efficiency, a measure of sensitivity) in the visible light spectrum.
You need to remove part of the light spectrum, a significant notch taken out of that, and create a light that people don't see as something that's unusual.
A team of engineers from the National Taipei University of Technology and Lakhtakia developed a method to produce periodically multi layered materials, similar to the lens in the peacock mantis shrimp, that are suitable for waveplates in the visual light spectrum and cannot delaminate because they are manufactured as one piece.
