Photo Research Releases Spectrascan® Spectroradiometer PR-788

PR-788 Features an Internal Neutral Density Filter, Allowing Users to Measure Higher Luminance Levels

SYRACUSE, N.Y. March 8, 2017 – Photo Research, a leader in world-class light and color measurement solutions, recently released its newest version of the PR-74X series of spectral measuring systems, the PR-788. The Spectrascan® PR-788, an extended dynamic range spectroradiometer, is used in Research & Development, Quality Control and Analysis, and production floor applications for flat panel display, automotive, aerospace and similar manufacturers.

The PR-788 provides an extended wide dynamic range of one million to one output. It measures the output of devices and tests any display or backlight at highest speeds available on the market, reducing the total time required to characterize and/or calibrate display products. The exposure time range for the PR-788 ranges from 7 milliseconds to two minutes. The PR-788 measures from black to full white, without the need to add external attenuation, due to the inclusion of an automated internal neutral density (ND) filter. With a single setup, PR-788 can be used to measure lower capability as well as higher level dynamic ranges. It measures spectral resolution capability for any display technology, from LCD to next generation display technology including laser projectors, with its industry-first Variable Spectral Bandwidth. This technology allows the user to automatically select spectral bandwidth down to 2nm. It also eliminates the need to change the measuring field size.

Like its predecessors (the Spectrascan® PR-740 and PR-745 Spectroradiometers), the PR-788 provides and measures radiance, luminance, irradiance/illuminance, radiant flux/lumens and radiant intensity/candelas by changing accessories. It is easy to use, with a high resolution, full color touch screen display that enables viewing of instrument setup and measured results, including a full-color Spectral Power Distribution graph of the sample. The PR-788 also connects and integrates with USB, RS232 and Bluetooth interfaces into an automated test environment. Remote-mode software enables control from custom applications, while the SpectraWin® Software allows measurement, graphical display results and data manipulation capabilities.

Typical applications for the PR-788 include backlight testing, OLED testing, laser projector calibration, and displays in the aerospace, computer and television industries.
