Chemically-Selective Detector and Methods Relating Thereto
First Claim
1. A method for adjusting the spectral detectivity of a thermal detector, comprising:
- coating the light sensitive portion of a thermal detector with a first material to reduce the response of the detector;
coating the first material with a second material that is thermally thin and has spectral absorption characteristics; and
coating the second material with a third material that is thermally thick,whereby the spectral absorbance of the second material as filtered by the third material primarily determines the thermal conversion of the thermal detector.

Abstract
In accordance with certain embodiments of the present disclosure, a method for adjusting the spectral detectivity of a thermal detector is described. The method includes coating the light sensitive portion of a thermal detector with a first material to reduce the response of the detector. The first material is coated with a second material that is thermally thin and has spectral absorption characteristics. The second material is coated with a third material that is thermally thick, whereby the spectral absorbance of the second material as filtered by the third material primarily determines the thermal conversion of the thermal detector.
