CM-20 Colorimeter

CM-20 Colorimeter

CM-20 Colorimeter provides four models, namely Low-luminance, Standard, High-luminance, and Wide-range, and each model can be equipped with a variety of test probes of different calibers, which can meet the testing requirements of a variety of display products.

CM-20 Colorimeter is equipped with a highly sensitive sensor, providing higher speed and higher precision display measurement, with a built-in lithium battery, which can be used offline! It can be used for handheld measurement anytime, anywhere, or fixed on a measurement bracket for fixed-point testing, or integrated into a test system on the production line, providing an efficient system integration test solution for display panel manufacturers!

CM-20 Colorimeter Characteristic

Ultra-low Luminance
Highly sensitive photoelectric sensor, low noise and innovative circuit design for ultra-low luminance detection, down to 0.0003cd/m2
It can be accurately measured from low luminance to high luminance, and the high luminance can reach 100000cd/m2

Ultra-high Speed
0.16 times per second @0.0003cd/m2,once per second @0.01cd/m2

Extreme Precision
The luminance accuracy up to 2%@0.01cdm2
The chrominance accuracy up to 0.003@0.01cdm2

Real-time Display
Display the test data in all directions with OLED screen

Easy to Integrate
Universal SDK/protocol for easy system integration and automatic measurement

CM-20 Colorimeter Advantage

  • For Gamma test, highly sensitive sensors and computing power enable color adjustment of products on the production line, effectively increasing productivity. 
  • It is possible to perform automatic single measurement and continuous multiple measurements.
  • Wide luminance measurement range: 0.0003~100000cd/m2, fast measurement of full range luminance through automatic gain control algorithm.
  • Flicker measurement, support VESA, JEITA, FMA and other modes.
  • Based on CIE1931 criteria, almost perfect visual function matching.
  • The OLED screen displays the measurement data in real time, and the measurement data can be transmitted through USB/RS232 connection to a computer.
