High-Accuracy Spectrophotocolorimeter System

This spectrophotocolorimeter test system is engineered for comprehensive photometric and colorimetric analysis of energy-saving lamps, fluorescent lamps, HID lamps (including high-pressure sodium and mercury lamps), LED sources, and phosphor materials. The system fully complies with international standards including CIE 177 “Color Rendering of White LED Light Sources,” CIE-13.3 “Method of Measuring and Specifying Colour Rendering Properties of Light Sources,” Optical Engineering 49-3-033602 “Color Quality Scale,” and IEEE recommended practices for LED current modulation.

• Measures and displays relative spectral power distribution (UV-VIS-NIR) P(λ), chromaticity coordinates, correlated color temperature, color rendering index, color difference metrics, peak wavelength, luminous flux, luminous efficacy, and other photometric parameters under PC control.

• Features automatic high-voltage adjustment to reduce measurement time and minimize instrument wear.

• Simultaneously monitors environmental and integrating sphere temperatures to ensure measurement reliability and data accuracy.

• Enables flexible exchange of chroma and color difference figures within test reports with full color display and printing capabilities.

• Provides spectral power distribution reports in English with RS-232-C interface compatible with all computer systems.

• LSP-500 AC Power Source with PC RS-232-C interface compatibility.
