The RoadVista Model 940D Computerized Photometric Range System is the ultimate in photometric testing of retroreflective materials, devices, automotive lighting 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 flexOptometer, 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.
The system can also be configured with the Gamma Scientific RadOMA spectroradiometer system to perform nighttime color measurements of retroreflectors and spatial color measurements of automotive lighting and light sources.
The Windows 7 compatible system software enables a single operator to perform highly accurate measurements in a matter of minutes. Simplifying 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 including LED's. Single, vector and matrix measurements are possible with easily programmed data collection macro sequence files.
Absolute measurements such as those recommended by ASTM, the Federal Highway Administration (FHWA), National Institute of Standards and Technology (NIST), the Society of Automotive Engineers (SAE) and the Federal Aviation Administration (FAA) can be performed with ease using the 940D computerized photometric range system.
For retroreflectance, the Model 940D software allows default measurement sequences conforming to ASTM E809 procedures A and B for retroreflective materials. The intuitive software simplifies measurements of devices such as warning signs, raised pavement markers (RPMs), pavement markings and post delineators.
An optional 5th-axis and rail mount system allow automated alignment of the system at different test distances between 5 and 30 meters (16 and 100 feet).
The system also allows SAE configurations for measuring light sources such as headlights, taillights and message and warning lights, including LED’s. Single, vector and matrix measurements are possible with easily programmed data collection macro sequence files.
