XYC-II All Digital Colorimeter

    The XYC-II All Digital Colorimeter is based on all digital integral photometric and colorimetric measurement technology. It has no analogue unit, thus it is very simple to overcome the zero drift which is impossible to be avoided in current colorimeter. The digital X(l),Y(l),Z(l) sensor has large dynamic range so that there is no range-changing error in it, moreover, it possesses strong anti-interference ability and high accuracy.
    The XYC-II All Digital Colorimeter contains internal RS232 computer interface, the calibration is done by software. It is suitable for monitoring and remote applications.
    The XYC-II All Digital Colorimeter software can calibrate the instrumentation, sample the data through RS232 interface and print out the results. it can also be calibrated by other standard light sources to obtain very high measuring accuracy of x,y color coordinate and color temperature. It is a real-time measuring system and run under Windows98/NT.

  The XYC-II All Digital Colorimeter has two types, Fig.1 can give illuminance value in addition, and Fig.2 can give luminous flux value.


    High speed measurement for  luminous flux, correlated color temperature etc. of incandescent lamp, halogen lamp, CFL, HID, LED, LCD screen
