Light source Incident Color Meter with accuracy similar to a Spectroradiometer
The CS-200 ChromaMeter measures luminance and chromaticity of light emitting products as diverse as large plasma displays, compact LCDs and LEDs, outdoor screens, high pressure lamps, and instrument panels.
The CS-200 is an instrument that enables highly accurate luminance and chromaticity measurements, comparable to those of a spectroscopic type of instrument while maintaining the simplicity, operability, and competitive price of a tristimulus type.
The CS-200 can be used for luminance and chromaticity measurement of various optical devices such as displays like LCDs, PDPs, organic ELs and FEDs, as well as light sources such as LEDs and lamps.
The CS-200 features 40 sensors and performs calculations using the spectral sensitivity characteristics (colour-matching functions) corresponding to the sensitivity of the human eye. 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 results.
Measurements over a wide range of luminance levels from a low luminance of 0.01 cd/m² through high luminance of 20,000,000 cd/m² (with measuring angle of 0.1°) can be carried out.
Three measuring angles can be selected: 1°, 0.2°, and 0.1°. The measuring angle can be switched according to the measurement target, ranging from display devices or other objects with large areas to measure, to objects with tiny areas to measure, such as car audio control panels, vehicle instrument panels, and compact LCDs.
Wide measuring range from low luminance to high.
Performance comparable to many Spectroradiometers.
Compact and lightweight. Battery power is also possible.

Data management software CS-S10w standard edition included.
Measurements can be synchronized with the display device by numerical input of the frequency. Selectable measurement speed (AUTO, LTD. AUTO, MANU, superFAST, FAST, SLOW and superSLOW)
Large LCD display with backlight
USB 1.1 communication
Data storage: 101 measured values (9-letter ID assignment possible) and 20 reference values
User calibration: 20 channels
Areas of application
Light sources of all types can be measured with the CS-200, for example signal, traffic lights, airport lighting, lamps, LEDs, picture tubes, LCDs, PDPs, etc., simply anything that emits light. With the ever-growing demand for diversified media, stimulated by the growth of information-technology business and full-scale service of digital broadcasting, research and development has accelerated for various display devices centring on plasma displays and LCDs. Innovations in LED technology have led to remarkable breakthroughs in the development of LED products including traffic lights, backlights for reflective LCDs, and large outdoor display screens.

At 0.2°measuring angle, the amount of received light is approx. 1/25 of that for 1°.
Therefore, the repeatability becomes the same as that for 1°with 25 times lower luminance.
