PR-880 Automatic Filter Colorimeter / ® Photometer The Reference in Color and Light Measurement

The PR-880 is designed for flawless precision and exceptional ease-of-use. Every function including multiple-mirror aperture positioning, dual filter wheels, detector zero and viewing system shutter are automated with precise motorized controls. Onboard microprocessor control- a powerful 16-bit, on board microprocessor controls all mechanical components, measurements and calculations. Results displayed on the 4 x 20 character backlit Liquid Crystal Display (LCD) enable at-a-glance analysis. Automatic internal calibration- the PR-880 features automatic calibration using an optically-regulated...

Measurement Capabilities Luminance Illuminance (Optional) Colorimetry Correlated Color Temperature L*u*v* ΔE* Source Refresh 40-250 Hz Full automation The PR-880 is the only fully automated filter photometer available today. We’ve automated the measuring apertures (5 standard sizes), the filter turrets, the measuring (zero) shutter and viewing (eyepiece) shutter. All of these features are controlled by an on-board computer and are accessed via 8 push buttons on the integral control panel. After setting up the measurement from menus on the 4 X 20 back lit LCD display, making a measurement is as...

The patented LR-127 LED Analyzer is a unique tool for making luminous intensity (in candelas) measurements of discrete LED’s for compliance to CIE 127 Condition A (2°) and Condition B (6.5°). During operation, the LED is inserted into a special holder that insures that it is securely mounted. Two holders are supplied and accept either T-1 (3mm) or T- 1.75 (5 mm) packages. Contact us for special configurations. Like all optical accessories for Photo Research instruments, the LR-127 is supplied with NIST traceable calibration from the factory and certified for accuracy for six months. There is...

ATE Environment RS232 connectivity and Remote Mode software makes it an easy task to incorporate the PR-880 into an Automated Test Environment (ATE). Whether measurement tasks are required in conjunction with a conveyor belt on a production line, linear stages used for an R&D test fixture (pictured at left), robotic parts handler, control of display output or other application specific hardware, the PR-880 ASCII (text) based command language simplifies the addition of measuring tasks to hardware control software. Features and Benefits Alignment Certainty Pritchard optics provide superior, non-...
