Six-axis robotic arm and spectroradiometer system captures measurements from any user specified angle while the display remains stationary.
The GS-940-7X Display Measurement Goniospectroradiometer System is the fastest and easiest way to perform high-accuracy angular measurements for any size display. With a six-axis robotic arm and high-speed spectroradiometer, the GS-940-7X scans screens from virtually any angle with 70 µm accuracy. The GS-940-7X is push-button simple to operate and program by a single technician.
Unlike traditional goniometers, the GS-940-7X keeps displays stationary during testing and can test multiple, unique displays at once. The GS-940-7x can withstand the rigors of 24/7 production floor environments, while still featuring a compact footprint and wheel mounted design for maximum mobility.
A state of the art spectroradiometer system (based on the RadOMA-DMS) with a precision robotic goniometer and sophisticated system software provide non-contact spectral measurement of a display as a function of position and viewing angle. The size of the measurement spot is determined by working distance (adjusted by the lens-focusing mechanism) and the field of view (FOV; selected by a six-position aperture wheel).
Spectral, Colorimetric, and Photometric results are automatically calculated and displayed by the system software; powerful report-generation features streamline documentation of results. The software also automates and manages system calibration, making it possible to maintain optimal system calibration with minimal downtime.
Setup is made easy by two unique system features: The robot automatically detects display position and orientation, and automatically aligns itself to the display, while a laser back-illumination system projects an image of the measurement spot on the display surface for easily visualization.
