Display Measurement Systems

  • Gamma Scientific Display Measurement Systems can capture spectral measurements of displays in milliseconds with ultra-low uncertainty. Any application which demands high sensitivity in the blue-light region, such as LED backlit displays, will benefit from the systems back-thinned CCD technology.
  • Display Measurement Systems from Gamma Scientific are available in six models covering multiple spectral ranges and featuring two different spectroradiometer configurations.
  • Interchangeable system components are available for easy customization and integration.
  • Gamma Scientific’s powerful Light Touch spectral data acquisition and analysis software package, available in both engineering/R&D and QC/production line versions, powers all Display Measurement Systems.
  • Original system calibration is performed in Gamma Scientific’s NVLAP accredited laboratory (NVLAP Lab Code 200823-0) using NIST-traceable standards. Gamma Scientific spectroradiometers can be self-calibrated and do not have to be returned to the factory for calibration.

RadOMA Dual Stage Cooled CCD Array
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.

Notes:

  1. Measuring 100% linearly polarized light through a Glan-Thompson Prism.
  2. Sensitivities are for a 10:1 signal-to-noise ratio based on the percent coefficient of variance measuring the luminance of a CIE Illuminant A source.

Standard Operating Range for Gamma Scientific Instruments:
– Temperature: Minimum: 0°C (32°F) – Maximum: 35°C (95°F)
– Relative Humidity (NonCondensing): Minimum: 20% – Maximum 70%
