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. The IR-cut filter is a short pass filter that blocks infrared light and transmits the visible; also based on an absorptive glass. The UV-IR cut filter is the combination of a UV cut and a IR cut in one single filter using a UV cut absorptive glass with a thin film layer system as an interference IR cut coating. |
