ProLight Opto has developed a series of high quality UV LED’s with quartz lens, aimed primary at curing industry where a stable, reliable, high power UV light is required, this is especially important in UV printing and medical curing applications. When the UV LED is turned on the photon from the radiative recombination will lose its energy due to refractive index changes therefore the choice of lens material is very important and ultimately determines the LED emitting efficiency and reliability. The most commonly used lens material is silicon but it has now been found that quartz gives better performance having the advantage of anti-yellowing ,better UV and heat resistance, and lower stress levels.
ProLight UV LED Quartz lens series use a special compound which has a low hygroscopicity, low stress levels and good weather resistance resulting in improved reliability.
ProLight offers a full series of 3535/5050/7070 emitter package and UV module series as per the table below.
