The Flir X8000sc / X6000sc thermal imaging camera series contains a four-slot, motorised filter wheel with automatic filter recognition and measurement parameter adjustment.
The removable filter holders also contain an integrated temperature probe for improved measurement accuracy.
Materials that are transparent or opaque to infrared (IR) wavelengths present problems in non-contact temperature measurements using a thermal imaging camera. With transparent materials, the camera sees through them and records a temperature that is a combination of the material itself and that which is behind it.
When a thermal imaging camera needs to see through an opaque material to measure the temperature of an object behind it, signal attenuation and ambient reflections can make accurate temperature reading difficult or impossible. In some applications, an IR filter can be placed in the camera's optical path to overcome these problems.
With the Flir X8000sc / X6000sc thermal imaging camera series the filter wheel enables application specific filters to be inserted between the lens and the focal plane. Each rotation of the filter position allows for a new spectral response to be measured.
