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.
