NVIS Spectroradiometer for Night Vision Devices from Optronic Laboratories

The OL Series 750-NVG, an NVIS spectroradiometer, is a specially configured version of the OL Series 750 Automated Spectroradiometric Measurement System for spectroradiometric and photometric certification of night vision compatible lighting devices. The OL 750-NVG, which exceeds the requirements of MIL-L-85762A, is a complete turnkey NVIS spectroradiometer system capable of extremely sensitive spectroradiometric and photometric measurements over the wavelength range of 380 to 930 nm. The system incorporates an extremely sensitive GaAs PMT signal detection system with a research grade single (OL 750S-NVG) or double (OL 750D-NVG) grating monochromator and direct viewing imaging optics. The high sensitivity in combination with the OL 750-423-NVG software enables the user to certify night vision compatible lighting devices faster and more accurately then previously possible. Depending on the level of the spectral radiance, the time required to scan over the wavelength range 380 to 930 nm at 5 nm intervals varies from 1 to 5 minutes. In order to enhance the portability of the OL 750S-NVG System, the optics head (monochromator/input optics/detector housing) can be optionally mounted on a rugged aluminum baseplate.
