Deposition Sciences Incorporated (DSI), a manufacturer of thin-film optical coatings, has unveiled its infrared (IR) reduction filter for imaging applications.
This IR reduction filter is designed to block IR wavelengths while transmitting the visible wavelengths in CMOS camera applications.
The IR reduction coating can be applied to glass as thin as 0.003in (0.08mm).
The filters can then be used as an encapsulating cover glass, increasing the signal-to-noise ratio for imaging devices being flooded with environmental IR light.
DSI's CMOS IR filter is claimed to block more than 95 per cent of the IR radiation, while transmitting more than 90 per cent of the visible radiation.
The introduction of this filter in a CMOS camera system can improve the signal-to-noise ratio.
It is suitable for use in imaging applications where it is critical that IR radiation is blocked, reducing the effects of extraneous light and improving contrast and clarity in the imagery.
DSI produces optical thin-film coatings via its Microdynsputtering technology.
The uniform optical coatings are stable over temperature and humidity changes, meeting the severe abrasion, adhesion, humidity and salt fog tests of Mil-C-675 standards.
