GS-1220-DMS Display Measurement System

GS-1220 Display Measurement Systems can capture spectral measurements of displays in milliseconds with ultra-low uncertainty. Any application that demands high sensitivity in the blue-light region, such as LED backlit displays, will benefit from the system's back-thinned CCD technology. Models are available in three configurations, covering spectral ranges from 250-900 nm, 360-900 nm or 360-1100 nm. Interchangeable system components are available for easy customization and integration. All systems come with our powerful Light Touch spectral data acquisition and analysis software package, available in both engineering/R&D and QC/production line versions.
