| |
Four adjustable measuring fields (0.1° ,0.2° ,1 ° ,2°) areselectable for all types of samples.
Designed for maximum sensitivity in measuring spot toaverage luminance.
The luminance, chromaticity, color temperature, CIELAB, CIELUV, and color difference are measured, and displayed at once.
Because the standard interface is built in , measurements can be performed automatically making it very suitable for inline use. (Please specify GP-IB/RS-232C during purchase)
Analog output enables continous measurement.
BM-5A offers high sensitivity by utilizing a Photo-multiplier
sensor.
BM-7 is a general standard type, and the BM-7FAST enables
high speed measurement. |
