Infrared Cut-Off Filters

FLIR color camera models are equipped with an additional infrared (IR) cut-off filter. This filter can reduce sensitivity in the near infrared spectrum and help prevent smearing. The properties of this filter are illustrated in the results below.

IR filter transmittance graph

Transmission Wavelength
T=50% 680 nm ±10 nm
T>80% 400 nm - 420 nm
T>85% 420 nm - 650 nm
T average 1% 750 nm - 1100 nm
T<3% 750 nm - 1100 nm

 

In monochrome models, the IR filter is replaced with a transparent piece of glass.

The following are the properties of the IR filter/protective glass:

Type   Anti-reflective
Material   Schott B270
Dimensions 14 ±0.08 x 14 ±0.08 mm
Thickness 1 ±0.07 mm
