GS-1290 NVIS System

 

Designed for manufacturers of military displays and other lighted instrumentation used in conjunction with night vision imaging systems (NVIS) that require their products to conform to MIL-STD-3009, the GS-1290-NVIS is an advanced, high-speed spectroradiometer that combines the leading-edge sensitivity of two-stage, cooled, backside-thinned CCD detector technology with the industry-renown RadOMAcam radiometric telescope from Gamma Scientific. The instrument exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009, covering the range of 360-930nm with six different field-of-view apertures. Original system calibration is performed in our ISO/IEC 17025 accredited laboratory by NVLAP (NVLAP lab code 200823-0), and through our Light Touch software, users with a known calibration standard can perform in-house calibration if so desired.

While competitive systems target a 10:1 signal-to-noise (SNR) measurement ratio, our GS-1290-NVIS spectroradiometers are designed and built to deliver SNR of 100:1 or greater. This increase in the performance level enables manufacturers to ensure that their products are fully compliant with the MIL-SPEC, without the downside of unnecessarily failing good product.
