To Define the Wavelength Range of Interest
Typical spectral response of standard PbS and PbSe detectors is shown below. By altering controlled chemical deposition parameters, Opto Diode can consistently produce detectors with very high peak detectivity or extended wavelength response at a given operating temperature. Cooling shifts both the spectral response and cutoff wavelength of PbS and PbSe detectors to longer wavelengths.
