Infrared Filters

Acrylic infrared filters are specially formulated to transmit infrared radiation at wavelengths greater than approximately 750nm and are therefore virtually opaque to visible light.

Infrared filters are suitable for use in systems which are triggered by near infrared signals, but which operate in environments where there is exposure to visible radiation. By eliminating the visible spectrum using an IR filter the signal to noise ratio is increased therefore improving the effectiveness of the system.

Features

Excellent transmittance up to approximately 90% in the IR region (850cm – 2000nm), 50% at 780nm and almost 0% in the visible spectrum
Optionally cast in non-glare finish to cut down surface reflections
Standard thicknesses of 0.5, 1, 1.5, 2, 3mm, non-standard available on request
Filters can be supplied to customer drawings
Acrylic filters can be machined to size and/or laser engraved
