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.
The UV-IR cut filter is the combination of a UV cut and an
IR cut in one single filter using a UV cut absorptive
glass with a thin film layer system as an interference IR
cut coating. |
