Flagship-Grade Hardware and Quality Control

Core Optical Components

Silicon Photodiode Array：

Features a dual-row 18-group silicon photodiode array. The large-area design ensures no saturation under strong light while maintaining high sensitivity under weak light. The spectral response covers 400-700 nm at 10 nm intervals, with a reflectance measurement range of 0-200%, accurately capturing visible light information.

Nanoscale Integrated Spectroscopic Device

Delivers nanoscale spectroscopic resolution, precisely separating light at different wavelengths to ensure high data accuracy across all spectral bands.

Full-Band Balanced LED Light Source + UV Light Source

The illumination source covers the full 400-700 nm spectrum, providing sufficient spectral distribution across the visible range to avoid gaps common in standard white LED sources. The integrated UV light source enables easy measurement of fluorescent materials, further enhancing measurement accuracy.

Flagship-Grade Hardware and Quality Control

Convenient Operation and Intelligent Interaction

1.Ergonomic Design and Easy Measurement

Ergonomically designed housing with a large touchscreen, optimized grip, and well-placed measurement button to accommodate different user preferences.

2.Precise Positioning and Calibration

Stabilizer Plate + Camera Framing Positioning
