A filter that transmits IR wavelengths and absorbs the UV and Visible range. It is widely used in IR light selection from visible light and applications include infrared alarm systems, night vision systems.

◦Transmission limit wavelength selectable at ranges from 760nm to 985nm.
◦It is used for a IR sensing camera by adding an IR transmitting filter onto an image sensor.
◦The visible and UV range can be blocked and the sensibility get higher by adding it onto an image sensor.

Guide

▶For a reflective type of filter, “cold mirror” we recommend (model CLDM) in our catalog.
W3116
▶We can provide similar products to custom specifications which are not mentioned on-line or in our catalog, please contact our Sales Division with your requests.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶The absorption wavelength range can not be used with high power laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter and there is a transmission loss of about 10%.
