1. A method for adjusting the spectral detectivity of a detector, comprising:
- coating the detector with a first material to reduce a response of the detector to light;
coating the first material with a second material that has a spectral absorbance; and
coating the second material with a third material, such that the spectral detectivity has a reduced contrast between a sample comprising a pure analyte and a sample comprising an interfering absorbance,whereby the spectral absorbance of the second material combined with a spectral absorbance of the third material primarily determines a sensitivity of the detector; and
wherein the detector is configured to detect an energy from the second material and not from the third material.

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.
