JapanTOPCONtopconBM-7luminance meterProduct Introduction:
BM-7 is a non-contact point of sight color brightness meter, commonly used for photometric testing in LED/LCD display screens, backlight sources, traffic signals, motor vehicle license plate lights, lighting engineering, film and television, construction and other fields. Fixed measurement field of view angle of 1 °.
JapanTOPCONBM-7luminance meterProduct Features:
The use of highly stable and spectral response curve strictly matched three color photoelectric detection components, as well as embedded microcontroller systems, low-power LCD displays, and large capacity lithium batteries, can not only meet the needs of laboratory use, but also be used for field observation. The instrument is equipped with a large aperture, high-quality telescope, which can measure the brightness and color of distant objects. After installing an auxiliary mirror, it can measure small objects at close range.
