XYL-VI Luminance Photoelectric Colorimeter

The XYL-VI Luminance Photoelectric Colorimeter implements a fully digital architecture, replacing traditional analog sensors with digital X(λ), Y(λ), Z(λ) spectral response sensors and substituting analog measurement systems with digital signal processing. This design eliminates analog components, thereby eliminating zero drift inherent in conventional colorimeters. The digital sensor configuration provides extended dynamic range, enhanced electromagnetic interference immunity, and improved measurement accuracy.

The XYL-VI Luminance Photoelectric Colorimeter incorporates an integrated RS232 interface for computer connectivity. Calibration procedures are software-controlled, facilitating remote monitoring applications. The instrument supports calibration via proprietary software for data acquisition and reporting, and can be referenced against standard illuminants to achieve high-precision measurements of x, y color coordinates and correlated color temperature. This real-time measurement system operates under Windows 7, 8, 10, and 11 environments.
