LM-7M Luminance Meter
LM-7M Luminance Meter, filter near CIE Y curve, which is the best device for measuring the Luminance of the displays. High sensitive silicon photodiode sensor for short distance and high precision luminance measurement. Luminance colorimeter measurement as low as 0.001cd/m2, standard measurement software, instrument continuous and interval measurement via computer control and view data through software.
LM-7Mluminance measurement deviceOverview
LM-7A Luminance MeterLM-7A Luminance Meter, optional desktop controller, robust and precise measurement devices, LCD display designed to show measurement values directly. The instrument can be calibrated and the measurement values are consistent with BM-7A/CS-2000. Conventional used for Luminance measurement on the production line. Optional probes with different measuring diameters. RS232 interface for remote monitoring of computer. Widely used in backlight modules, LCD displays, OLED, various FPD, and optical material measurement.
