Contrast Measurement System
Hoffman's LM-33-52 Contrast System is designed for testing as required by MIL-L-85762. This system consists of a direct light source focusing 10,000 foot-candles at 5000° Kelvin on the display surface, a diffuse light source providing 2000 fL 30° off-axis to the same display, and a modified Meter Mover to accommodate the photometer and test system light sources.
