GS-1290-NVIS Dual Stage Cooled Spectroradiometers

RadOMA Dual Stage Cooled CCD Array Spectroradiometers are 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.

While the MIL-SPEC and 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 in the metrology system enables manufacturers to ensure that that their products are fully compliant with the MIL-SPEC, without the downside of unnecessarily failing good product.
