Colorimeter FMS10

Applications
Tristimulus colorimeter for color measurement on primary light sources; e.g., lamps, luminaries, light signals, flares, monitors, displays, glasses, and filters.

Colorimeter of highest precision for absolute measurements with the tristimulus method according to DIN 5033 section 6 and CIE Publ. No. 15.2 (1966), respectively.

Characteristic

Microprocessor-controlled tristimulus colorimeter with 4 spectrally matched silicon detectors equipped with graphic LC display with backlight illumination

Special Feature
New FMS10-14: Small light sensitive surface of just 14 mm available with remaining sensitivity for measuring directional light sources with uneven light distribution; this offers the unique advantage of ensuring that detector is fully illuminated, thus guaranteeing correct measurement results.
