Luminance Colorimeter

The XYL-VI Luminance Photoelectric Colorimeter thoroughly modernizes the traditional design by incorporating digital X(λ), Y(λ), Z(λ) sensors, replacing conventional analog sensors. It utilizes a digital signal measurement system, eliminating the analog unit, thus effectively addressing zero drift issues common in traditional colorimeters. The digital sensor offers a wide dynamic range and robust anti-interference capability, ensuring high measurement accuracy. The XYL-VI Colorimeter features an internal RS232 computer interface and software-based calibration, making it suitable for monitoring and remote applications. It can be calibrated using XYL-VI software or other standard light sources to achieve precise x, y color coordinates and color temperature measurements. The system operates in real-time on Win7, Win8, Win10, and Win11 platforms. • Luminance Y: Digital V(λ) sensor with relative spectral sensitivity: f1<5.5%, dynamic range: 10~1,000,000 cd/m², accuracy: <5%, sensitivity: 0.01 cd/m², repeatability: 0.01 cd/m² • Measuring angle: 1 degree, measuring distance: 0.7m to infinity • Color Coordinates x, y, u, v(u’, v’): (Luminance > 10cd/m²) Accuracy(x, y): ±0.002 (CIE Standard A-source, 100cd/m²), repeatability(x, y): ±0.0005 (CIE Standard A-source) • Color Temperature Tc: (Luminance > 10cd/m²) Dynamic range: 1350~25000K, sensitivity: 1K, accuracy: ±20K (CIE Standard A-source, 100cd/m²) • Temperature effect: -0.1%, no range-changing error • Refresh frequency: 1n/s (≥10 cd/m²), 1n/3s (<10 cd/m²) • 128×64 LCD display with data hold function • RS232 computer interface and software • Power Supply: 9V Battery, 6V DC adapter • Size: 270*95*225(mm) (Tripod optional).
