Feature

Precision Optical Measurement System
Optical geometry: The 45/0 illumination method (45° circular uniform illumination, 0° reception) is adopted, which complies with standards such as CIE No.15, GB/T 3978, and GB 2893 to ensure measurement standardization and data consistency.

Combined full-spectrum LED light source: It employs a combination of 400-700nm full-spectrum LED light source and UV light source, ensuring sufficient spectral distribution within the visible light range, avoiding spectral loss in specific wavelengths, preventing saturation under strong light, enhancing sensitivity under weak light, and allowing for easy measurement of fluorescent samples.

Silicon photodiode dual array (40 groups) sensor: Using larger area silicon photodiode array (40 groups in two rows) sensor effectively solves the problems of strong light saturation and weak light detection, ensuring the instrument's measurement speed and accuracy.

High-precision colorimetric control, inter-station difference ≤0.15

Repeatability accuracy：Within ΔE*ab 0.018，The repeatability accuracy of the instrument has reached a level that is difficult for similar products to match.

Inter-instrument Error: Within ΔE*ab 0.15，Ensure the measurement results from multiple devices are highly consistent.
