Color luminance meter CS-200

Model：CS-200
Brand：

With this newly developed spectral fitting method, tristimulus values (XYZ for red, green, and blue) with a far higher accuracy than those of conventional tristimulus colorimeters can be obtained, providing excellent accuracy. Measurements over a wide range of luminance levels from a low luminance of 0.01 cd/m2 through high luminance of 20,000,000cd/m2 (with measuring angle of 0.1°) can be done.
·Three measuring angles can be selected: 1°, 0.2°, and 0.1°. CS-200 is particularly suitable for the various types of light source measurement.
·High measurement accuracy
·With the newly develop spectral fitting method, it guarantee the same high precision at measuring, which is similar to a spectroradiometer.
·Parasitic light between lens and measuring point can be filtered by aperture that makes measurement result more precise.
·Synchronies of measurement and display
·Wide measurement range
·Measurements over a wide range of luminance levels from a low luminance of 0.01 cd/m2 through high luminance of 20,000,000cd/m2 can be done.
·High repeatability is achieved by spectral fitting method and precise configuration.
·Selectable measuring angle
·Three measuring angles can be easy and fast selected: 1°, 0.2°, and 0.1° according to the measurement target.
·Compact and lightweight, battery power is possible
·Handheld operation is achieved by designs of compact, lightweight and battery-driven. It can use AC adapter as well ·Applications: Display in large or medium size; small light source; tiny source of long distant light.
