To meet growing customer demand for routine calibration of laser and optical-fiber power meters (OFPMs), we have developed two additional calibration services based on comparisons with pyroelectric detectors for absolute responsivity of fibercoupled power meters and relative spectral responsivity.
Because room temperature thermopiles and pyroelectric detectors do not have high enough sensitivities to measure weak signals from monochromators, HgCdTe detectors were selected as working standards for the 5 [micro]m to 20 [micro]]m wavelength range.
Since the pyroelectric detector surface is highly optically opaque, this results in the reconstruction of a narrow spike appearing at the back surface of the sample.
Prior to this work, extension of the detector responsivity scale to the NIR spectral region relied on the use of a spectrally-flat pyroelectric detector to determine the relative responsivity of NIR working standard detectors, i.
