The Sanyuanse 8mm Aperture Spectrophotometer is a mainstream color measurement device that strikes an optimal balance between versatility and precision. Capable of accommodating the color measurement needs of the vast majority of standard-sized samples, it has become the preferred instrument for color quality control across various industries, thanks to its stable optical performance and standardized measurement aperture.
It enables the efficient execution of precise color measurements and color difference management.

Core Product Parameters

• Measurement Aperture: Φ8mm standard universal aperture, suitable for testing the vast majority of standard-sized samples.

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

• Measurement Parameters: Accurately outputs standard colorimetric values—such as Lab, LCh, and XYZ—as well as core data points including total color difference (ΔE) and individual color difference components.

• Measurement Accuracy:High repeatability (ΔE ≤ 0.005) and excellent inter-instrument agreement (ΔE ≤ 0.1), ensuring highly accurate and consistent measurement data.

• Wavelength Range: Covers the full visible spectrum (360–780 nm), allowing for the comprehensive capture of a sample’s spectral information.

• Measurement Speed: Single measurement completed in ≤ 1 second, facilitating rapid, continuous testing of large batches of samples.

• Light Source Configuration: Features a high-performance pulsed xenon lamp; complies with various international standard illuminants (e.g., D65, A, F), offering exceptional durability and stability.

Core Product Advantages

The 8mm universal measurement aperture balances measurement precision with coverage area, effectively avoiding the inefficiencies associated with small apertures and the susceptibility to interference inherent in large apertures. It establishes stable contact with the surfaces of various standard samples, thereby eliminating issues such as light spot displacement and data distortion.
The instrument accurately adapts to a wide range of surface textures and finishes—including matte, high-gloss, metallic, pearlescent, and textured materials—completely eliminating errors associated with subjective visual color assessment. It supports the storage, export, comparison, and digital archiving of color data, facilitating standardized color management throughout the entire production workflow. With its user-friendly operation and robust stability, it is ideally suited for deployment in diverse environments, ranging from laboratory settings to production lines.

Applicable Products and Scenarios

Suitable for the color measurement of the vast majority of standard-sized products, with extensive applications across industries including coatings, plastic sheets, textile fabrics, leather, printed paper products, ceramics, furniture, automotive interiors, plastic casings, and cosmetic packaging.
It is applicable to color matching and formula development, color difference control for production batches, finished product quality inspection, supplier color harmonization, and the digital archiving of color data; serving as a versatile, high-precision color measurement tool for industries such as coatings, textiles, printing, plastics, and home furnishings.
