Applications of Hemispherical UV LED Condenser Lens :
LED can be packaged with quartz glass lens to improve LED illumination, and no loss of UV penetration, quartz glass transmittance up to 99.9%. compared with the traditional silica lens, quartz glass is not easy to yellow and fall off, so the LED performance is more stable, longer service life.
