OL 770-NVS Display Test and Measurement System

The OL 770-NVS Display Test and Measurement System is specifically configured for spectroradiometric certification of NVIS compatible lighting systems. Consisting of the OL 770VIS/NIR Spectroradiometer and the OL 620-NVS CCD Imaging Telescope, it is a complete turnkey system capable of making fast, accurate spectroradiometric measurements over the 380nm to 1100nm wavelength range. Users are able to quickly certify NVIS displays and sources as being in compliance with MIL-L-85762A and MIL-STD-3009.

The OL 770VIS/NIR Spectroradiometer is a high-speed, multi-channel spectroradiometer utilizing a cooled CCD detector in one rugged, portable package. The internal spectrograph is based on an aberration corrected, concave, flat field grating that operates over the 380 nm to 1100 nm wavelength range. Optical input to the spectrograph is made via fiber optic connection. The standard slit supplied is 350 microns, which meets or exceeds all measuring equipment required.

The OL 620-NVS Imaging Telescope utilizes a direct viewing optical design. An internal CCD camera provides real-time viewing of the measurement spot and surrounding image area for precise focus and alignment. A “snapshot” of the image area can be saved with the measurement data. The OL 620-NVS operates via USB interface and is optically coupled to the OL 770VIS/NIR Multi-Channel Spectroradiometer via the supplied 600 µm fiber optic. The standard fiber optic length is 1.5 meters. Optional 2.0 m – 10.0 m lengths are also available.

The Application Software provides the user with easy and complete access to the system’s full power and capabilities. Features include:

Active zoom view CIE diagram with customizable lighting requirement boundaries
Ability to see all PASS/FAIL conditions for all lighting requirements for a specification simultaneously
Fast access to all NVIS data, even while the instrument is continuously measuring
Editable NVIS requirements to modify the current specification or add new ones.
Support for MIL-L-85762A, MIL-STD-3009, and UK Working Paper 6 included
Dynamic direct Microsoft Excel and WordÔ reporting of NVIS results
Image storage of sample measured with each measurement
Detailed feedback on why a device under test (DUT) failed a lighting requirement
NVIS Ga and Gb weighted spectral radiance graphs
