View our latest versions of this instrument, the CS-150 and CS-160.

The CS-100A Color and Luminance Meter is a portable tristimulus colorimeter for measuring any illumination source, whether it's a traffic light or a xenon lamp. The CS-100A luminance and color meter allows luminance and chromacity to be measured remotely with an acceptance angle of 1°. It is the perfect marriage of efficiency and ergonomics with regards to spot measurements of color and luminance in a handheld portable instrument. The ultra-portable Konica Minolta color and luminance meters can also measure the brightness and color of the light.

The CS-100A color and luminance meter can measure nearly any type of light source, indoors or out. The CS-100A is incredibly precise, designed for portability, and minimizes measurement time. It is a tristimulus spot meter used to measure the luminance and color values of colored light sources. It serves the same purpose as the LS-100, but with the added bonus of a color measurement option. The CS-100A luminance and color meter has an optical system that allows precise targeting and ensures that the viewfinder shows the exact area to be measured, even up close. The view finder on the CS-100A shows the measured luminance value measurement field as well as the measurement environment. We have also given special attention to minimize flare.
