The RoadVista Model 940D Computerized Photometric Range System is the ultimate in photometric testing of retroreflective materials, devices and light sources. It allows the material engineer and the light source designer to characterize their products, whether purchased and developed in-house.
When used in conjunction with Gamma Scientific's Model FM-100 Flash Measurement Photometer or Model DR-2000 Photometer, the system allows photometric measurements that determine the effective intensity of red and white strobe type anti-collision lights for aircraft and integrated illuminance energy in units of LUX seconds (lumen/m² per second) and luminous intensity energy (candela second) for barricade and other flashing lamp sources.
New system software enables a single operator to perform highly accurate measurements in a matter of minutes. For example, perform absolute measurements with ease. Simplify retroreflectance measurements via default measurement sequences conforming to ASTM E809 procedures A and B for retroreflective materials. Or utilize SAE configurations for measuring light sources such as headlights, taillights and message and warning lights. Single, vector and matrix measurements are possible with easily programmed data collection macro sequence files.
