Handheld Luminance Meter uNIT-LL Gamma Scientific

This bundle combines a photopic sensor with a fixed-focus lens to provide non-contact measurement of an area on the display surface. Spot size is dependent working distance, which ranges from 17 mm to infinity. 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 handheld portable optometer. Measurement results are displayed by the optometer in units of footlamberts or cd/m², and digital data can be acquired directly via PC.
