PR-920 Digital Video Photometer Innovation - Photo Research developed the first commercially available video photometer over 15 years ago. We are proud to introduce our newest and most advanced video photometer - the PR-920 Digital Video Photometer (DVP). Our video photometers feature the patented Synthetic Aperture data analysis method and numerous other patents and are beng used world-wide for applications rangmg from FAA testing of radar screens to ISO certification of information dis* plays. Digital Prcision - The heart of the PR-920 is a thermo-electrically cooled. 1024 x 1024 響lment digital CCD camra which helps to make it the most accurate, sensitive and repeatable video photometer in rts class. Because the PR-920 detector consists of 1.048 million pixels, excellent spa驭tial resolution is guaranteed. Hand Matched Filters - In addition to the proprietary camra design, the detector response of each PR-920 is painstakingly matched to the CIE V(X) (photopic) response by our proprietary fitter matching techiques that have been devel- 6 32 m (16.1 cm» o p e d VideoWin 3* with 3D luminance graph over the last 50 years. Our filter matching exprience, combined with an individual calibration of each and every detector 驩lment means that the PR-920 delivers the most accurate measurement results of any commercially available video photometer In addition to the standard photopically matched filter, the PR-920 can be equipped with high* accuracy, hand-matched CIE Tristimulus filters (option CFS-302). Versatility - The PR-920 is the only commercially available video photometer that utilizes a focusable objective lens as standard equipment r 81 in (19 8 cm providing the capability of addressing virtually any application without changing lenses- The PR-920 is also the only video photometer that includes 5 intemally mounted, fijlly automated neu-tral density filters giving it the widest standard luminance range of any instrument in ifs class. Standard Equipment - System - Optical Head. PCI Frame Grabber and Cables; Optical Head - CCD Cam魩ra, Dual Filter Turrets (CIE Photopic and 5 Neutral Density filters); Calibration - Certification and Instruction Manual. VideoWin m3 software must be ordered separately.
