cs-2000 spectroradiometer

World’s Top Level Capability To Detect Extremely Low Luminance

Konica Minolta spectroradiometer CS-2000 is a highly accurate spectroradiometer for any light sources in terms of spectral power distribution data, luminance, chromaticity, color temperature (CCT), dominant wavelength (DW), excitation purity (Pe) etc. 

CS-2000 spectroradiometer is built to pick-up incredibly low luminance ranges that reach 0.003 . This polychromator type spectroradiometer has the ability to measure 100,000:1 contrasts. Many recent FPD models are designed for better black level representation or better contrast in order to provide higher quality images.

Spectroradiometer CS-2000 signal processing technologies and optical design give you accurate measurements of luminance and chromaticity levels, including extremely low levels. The instrument calculates measurements in only 5 seconds. The spectroradiometer measurement calculation abilities free you of the need to work with electrical and mechanical noise elements.

3 selectable measurement angle (1°, 0.2°, 0.1°). The measuring angle can be adjusted according to the measurement target or application.
