GS-1290-DMS display measurement spectroradiometers represent the state-of-the-art in speed and accuracy, with the highest dynamic range in an array-type spectroradiometer available. The system offers 1,000,000:1 contrast measurements for a single measurement aperture and luminance measurements down to 0.0005 cd/m2 .
Any application that demands high sensitivity in the blue-light region, for example LED backlit displays, will benefit from this system’s back-thinned CCD technology. The optical viewing system also back-projects the measurement aperture, superimposing the measurement spot on the DUT, which is both visible on the DUT or on the host computer via a USB 2.0 camera.
