The Smaller the Better
|
|
We are all familiar with the saying "Good things come in small packages". This has
never been truer than with the new PR-905 Digital Video Photometer. The PR-905 system
consists of a 1024 x 1024 digital CCD camera, camera power supply, PCI frame
grabber with cables, and system software VideoWin™.
Best of all, because the PR-905 is a Photo Research product, quality and performance
are guaranteed. Mate the PR-905 with positioning stages (up to 5 axes) for the utmost
in measurement flexibility.

Low Cost Solution
|
|
The PR-905 is the low cost solution to your CCD photometer applications and features
many of the same capabilities of the PR-920 at a fraction of the price. The PR-905
provides high accuracy photometric and spatial measurements while staying within
today's shrinking budgets.

VideoWin™ Software
|
|
A key component of any video photometer system is the hardware control / data analysis
software. This is the "brains" of the system and determines how the image is captured,
and how the captured image is analyzed. VideoWin™
utilizes the patented Optimize data capture algorithm that, as the name implies,
optimizes the optics and detector exposure time for the available signal. We've
also included a variation that enables the user to optimize the system to specific
areas of the image. This provides great flexibility to displays that exhibit a wide
range of output levels. Both packages can export calculated results (luminance,
chromaticity, uniformity) to specified cells in an Excel spreadsheet. Helps automate
measurement sequences, including exporting data to Excel, using "point-and click"
macros.
VideoWin™ is designed to analyze flat panel displays
such as LCDs, OLEDs, PDPs, ELPs and edge-lit / backlit technologies.
