RadOMA NVIS Spectroradiometer

The GS-1290-NVIS is an advanced, high-speed spectroradiometer that combines the leading-edge sensitivity of backside-thinned CCD detector technology with Gamma Scientific’s industry-renowned RadOMA opto-electrical platform.

The GS-1290-NVIS is specifically configured for ANVIS testing of cockpit displays and lighting. It exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009.

The GS-1290-NVIS represents the state-of-the-art in speed and accuracy in a commercially available spectroradiometer. Measurements that required a few minutes in the past with scanning grating spectroradiometer systems can now be performed in a matter of seconds.

 


 

Part of the RadOMA platform family – a durable optoelectrical design proven in hundreds of facilities worldwide – the GS-1290-NVIS shares the same feature-rich functionality as its siblings which includes: automatic dynamic range optimization that ensures system electrical gains are always set for the best results; USB 2.0 interface; and Gamma Scientific’s powerful 32-bit Light Touch spectral data acquisition and analysis software package. The GS-1290-NVIS configuration covers 380-930 nm and includes 6 different field-of-view apertures.
