Phot research spectrametrics model pr-1530AR anvi spol
The NviSpot Night Vision Radiometer/Photometer/Colorimeter is a multipurpose instrument designed to meet the NVIS radiance light measurement compatibility requirements of MIL-L-85762 for NVIS applications, and also perform the conventional fast and accurate luminance and colorimetric light measurements long associated with the PR-1500 SpotMeter
It consists of a modified Pritchard-type filtered photometer system with interchangeable objective lenses and an internal calibration source. For NVIS measurements it includes a proprietary filtered, extended-red gallium arsenide photomultiplier tube with overload protection, threshold detection and an NVIS-compatible digital display readout. Although the NVISpot does not replace the requirement for a laboratory-grade spectro-radiometer specified in the MIL Spec, it does provide a relatively inexpensive and highly accurate means of light measurement for all phases of production and control testing.
