The Sanyuanse 4mm Aperture Spectrophotometer is a high-precision color measurement instrument specifically engineered for small-area and miniature samples. Focused on the need for precise color analysis of minute objects, it perfectly resolves the industry-wide challenge where conventional large-aperture instruments fail to accurately measure small-sized samples, thereby enabling precise, digitized color management for miniature items through professional-grade performance.

Core Product Parameters

• Measurement Aperture:Φ4mm—a specialized small aperture designed for the inspection of extremely small-area samples.

• Optical Structure: Employs a d/8° integrating sphere geometry, supporting dual-mode measurement: SCI (specular component included) and SCE (specular component excluded).

• Measurement Parameters: Accurately outputs chromaticity values ​​such as Lab, LCh, and XYZ, as well as ΔE color difference values; captures complete spectral data for the sample.

• Measurement Accuracy: Repeatability of ΔE ≤ 0.05; Inter-instrument agreement of ΔE ≤ 0.1—ensuring stable and reliable measurement data.

• Wavelength Range: 360–780nm (full visible spectrum), covering the requirements for a wide variety of standard color measurement applications.

• Measurement Time: Approximately 1 second per single measurement, enabling efficient and rapid color analysis of small samples.

• Light Source Configuration: High-energy pulsed xenon lamp; complies with various standard illuminants (e.g., D65); features a long service life and exceptional measurement stability.

Core Product Advantages

Thanks to its compact and precise measurement aperture, this 4mm spectrophotometer can make intimate contact with the surfaces of minute samples, thereby preventing data deviations caused by light-spot overflow—effectively eliminating the subjective errors inherent in visual color assessment.
The instrument is capable of analyzing a wide range of surface textures—including matte, high-gloss, metallic, and pearlescent finishes. Whether dealing with tiny flat surfaces or irregularly shaped miniature samples, it delivers precise color and color difference analysis. Furthermore, it supports data storage, export, and digital archiving, meeting the comprehensive requirements of the entire quality control workflow.

Applicable Products and Scenarios

Specifically designed for the color measurement of small-sized and intricate samples, this instrument is widely applicable to products such as electronic components, plastic granules, small hardware fittings, ink color spots, miniature jewelry, fine textile yarns, small cosmetic samples (pastes/creams), and precision plastic parts.
Suitable for the development of precision color-matching formulas, color difference control for small-batch samples, quality inspection of finished micro-components, and the standardized archiving of color data, this specialized device serves as an ideal tool for high-quality color management in industries such as electronics, hardware, fine chemicals, and textile accessories.
