RadOMA Spectroradiometer

  • Product No:GS-1220
  • Manufacturer:Gamma Scientific

RadOMA GS-1220 spectroradiometers are optimized for quality control and high speed LED testing applications, with up to 100 ms optical integration time.

The GS-1220 spectroradiometer features a proprietary optical design and back illuminated CCD technology that provides exceptional low-light measurements, superior blue light sensitivity and highly accurate measurements of wavelength, color and power.

The 2048 pixel back illuminated CCD is temperature cooled for superior instrument repeatability.

Original system calibration is performed in Gamma Scientific’s NVLAP accredited laboratory (NVLAP Lab Code 200823-0) using NIST-traceable standards.
