Gamma Scientific Display Measurement Systems can capture spectral measurements of a variety of display systems with high accuracy. Any application which demands sensitivity in the blue-light region, such as LED backlit displays, will benefit from the system's back-thinned CCD technology.
Gamma Scientific's Display Measurement systems are available in multiple models covering different spectral ranges and spectroradiometer configurations.
Based on the GS-1220 and GS-1290 instruments, the systems use interchangeable components for easy customisation and integration, while powerful spectral data acquisition and analysis software makes them ideal for calibrating any type of display:
LEDs, LCDs & Plasmas
Near eye systems
Projection screens, HUDs
Production line sampling
OEM display inspection
Calibrate any display
Brightness / uniformity
True colour determination
Luminous Intensity (15 kcd max)
Spectral ranges (nm)
AVS or Reflex
Wavelength and colour accuracy
Low polarisation error
User-selectable half power bandwidth
Windows™ control/analysis software

Gamma Scientific Display Measurement System GS-1220
Spectroradiometers for display testing - the GS-1160 Series
Gamma Scientific offer two instruments for colour, intensity and flicker testing of all types of LED, LCD, OLED and Quantum Dot screens.
The GS-1160 is the touchscreen-equipped handheld version, while the GS-1160B is designed for the bench and operates in conjunction with PC-based analysis software. The GS-1160 can also be used as a desktop system as it is supported by the same software.
These new spectroradiometers deliver faster results with repeatability superior to filter-based instruments. Measurement capabilities include Colour Chromaticity - both CIE 1931 and CIE 1976, Gamma, White Balance Adjustment, Contrast, Flicker (VESA & JEITA), and Uniformity. With luminance measurement ranges from 0.05 to 5000 cd/m² and fast millisecond integration times, the GS-1160 delivers a cost-effective superior performance.
Data is output on both via USB, or can also be stored on an SD card in the GS-1160 portable model. The GS-1160B can be programmed for custom testing as it has an Application Programming Interface (API). Commands can be sent via RS-232 or the USB.

Near Eye Display Test System - GS-1290 NED
Gamma Scientific's Near Eye Display (GS‐1290 NED) measurement system is designed to accurately capture spectral measurements of VR and Helmet mounted displays as viewed by the human eye.
Gamma Scientific's Near Eye Display measurement system is designed to accurately capture spectral measurements of Virtual, Mixed, and Augmented Reality headsets plus helmet mounted displays as viewed by the human eye.
These types of display require precise measurement of light in the virtual image field of view, and the GS-1290 NED system is the culmination of decades of experience in developing display and HUD test systems for military aviation.
It combines Gamma Scientific's trusted GS-1290 spectroradiometer with optics compact enough to fit within a test rig based on the dimensions of a typical adult human head, thus enabling easy measurements of the left and right eye's view for:
Luminance and colour uniformity
Symbology luminance and colour
Left/Right eye parallax
Response time/flicker and MTF are also available as options
Original system calibration is performed in Gamma Scientific’s NVLAP accredited laboratory using NIST-traceable standards. Gamma Scientific spectroradiometers can be self-calibrated and do not have to be returned to the factory.
