Reflex Luminance Meter uNIT-R Gamma Scientific

This Telephotometer bundle combines a photopic sensor with a reflex viewing system and a standard camera lens to provide non-contact measurement of a precisely-defined spot on the display surface. The user can view an image of the measurement spot superimposed on the display.

Spot size is determined by working distance (adjusted by the lens-focusing mechanism) and the field of view (FOV). This system is suitable for the following types of test and measurements: Luminance, Contrast Ratio, Gamma (Gray Scale/EOTF).
The system’s luminance calibration is programmed into the benchtop optometer. Measurement results are displayed by the optometer in units of footlamberts or cd/m², or digital data can be acquired directly via PC.
