The SS450 Multi-Spec Display Measurement System provides the ability to make color, contrast, luminance, uniformity and gamma measurements at numerous locations instantly. The measurements are made with either a standard lens configuration for large screens, or a cosine diffuser option for measuring the projection engine directly (lux) without the use of a screen.

The SS450 system is excellent for production applications and for any testing where short test duration is crucial. For example, a 16-point uniformity test can be performed instantly. There will be no time wasted waiting for a positioning system to travel across the screen.

These measurements are all accomplished using a diffraction grating spectrometer, eliminating filter-matching errors inherent to color filter measurement systems. Microvision’s multiple detector configuration also eliminates lens correction problems found in single lens systems that collect data on the entire display in one "snapshot".

The system uses the newly developed "multi-spec" selection process  to monitor points on the plane of the projected image. Detectors are mounted on a transparent panel placed in front of the display or at the focus point of the projection engine. Up to 16 detectors can be used and the detector location can be quickly and easily changed. A pattern generator can be  integrated with the SS450 to drive the Unit Under Test and automatically present the proper test pattern.

The SS450 can also be used for multiple panel testing. For example, two side-by-side UUT's can be set up and alternatively tested, thereby decreasing test time. Similarly, the same panel may be set up to measure two different sizes of displays. With up to 16 detectors, some can be set up for large displays while the rest can be set up for smaller.

The user can quickly and easily program the system to only collect data at the desired detectors. For instance, 5-point and 9-point tests can quickly be programmed without having to move detectors. The results of these measurements can be posted to a spreadsheet with pass/fail criteria.

The SS450 is unique in its ability to perform extremely fast testing on any size display. For projection systems, measurements can be made with or without the screen in place.

The cosine diffuser option will allow the user to measure the projection engine directly. In either case, the spectrometer based test results are returned quickly and accurately for high throughput and quality.
