UV cutting filter(or UV blocking filter) :
Application: CMOS digital cameras,
Substrate:Soda Lime Glass
Blocking undesirable UV radiation allowing excellent visible transmission.
UV-cut filters are long pass filters that block the UV wavelength range and transmit the visible. These filters use an absorptive glass, which is robust, cost-effective and insensitive to angle of incidence. In machine vision applications they are used in front of a lens on a CCD or CMOS camera to protect the sensor from UV light, in absence of internal protection in the camera. In addition, they are often used to protect expensive lenses from potential damage.
