A near-IR radiometer standard with similar performance to silicon trap detectors has been developed to calibrate detectors and radiometers for absolute spectral power, irradiance and radiance responsivities between 950 nm and 1650 nm. The new radiome

Changes in beam geometry during the calibration and subsequent testing of optical detector standards can cause errors which appear as uncertainties in the responsivities of the detectors. These uncertainties, caused by non-ideal detector input charac

We built a large-area domain-engineered pyroelectric radiometer with high spatial and spectral response uniformity that is an excellent primary transfer standard for measurements in the near- and the mid-infrared wavelength regions. The domain engine

Glass filter packages were designed to cut out UV-A band (320 - 400 nm) using GaP photodiodes and UV-B band (280 - 320 nm) with solar blind phototubes. UV diffusor plates were applied in input optics for cosine correction. Probes are calibrated to eq
