Reflex Reflector Measurement Systems

Photometric Solutions International Pty Ltd

The measurement setup involves using a projector to illuminate the test item, and then measuring the luminous intensity of the light reflected from the test item. The ratio of the luminous intensity emitted by the reflector (in candelas) to the illuminance on the reflector (in lux) is the coefficient of luminous intensity or CIL (cd/lx).
