1. Introduction
In modern industrial production, color, as a core evaluation index of product appearance quality, runs through the entire process from raw material procurement, production and processing to finished product inspection. As a key tool for quantitative color detection, color measurement instruments have been widely used in many industries such as printing, coating, textile and plastic. Traditional color measurement instruments have problems such as insufficient accuracy, complex operation and large inter-instrument differences, which are difficult to meet the needs of high-precision production and rapid detection. Having been deeply engaged in the color measurement field for many years, LISUN GROUP has launched the HSCD-860 Handheld Spectrophotometer (High-Precision Reflection), which has broken through the limitations of traditional equipment through technological innovation and become a representative product in the field of color measurement instruments. Combining the technical parameters and practical application scenarios of this product, this paper deeply discusses its core advantages and industry application value.

2. Technological Innovation of Color Measurement Instruments——Core Breakthroughs of HSCD-860

2.1 Nano-Integrated Optical Technology, Leading the Innovation of Spectroscopic Devices

The HSCD-860 has achieved a major breakthrough in spectroscopic technology. It adopts a 5-micron thick nano-integrated optical device developed after nearly 10 years of research. It can achieve nano-level spectroscopic capability only with an ultra-thin optical structure, successfully breaking through foreign technological blockades. Compared with the prism or grating spectroscopic schemes adopted by traditional spectrophotometers, nano-integrated optical devices not only greatly reduce the instrument volume, but also improve the spectroscopic accuracy and stability, providing core technical support for the miniaturization and high-precision development of color measurement instruments.

2.2 Dual-Optical Path Design, Ensuring Measurement Stability

This color measurement instrument innovatively adopts a dual-optical path design. While measuring the sample signal, it real-time monitors the light source energy fluctuation, effectively offsetting the measurement error caused by environmental interference and light source attenuation, and increasing the instrument’s repeatability accuracy to an ultra-high level of dE*ab≤0.03. The application of the dual-optical path design solves the industry pain point of precision drift of traditional single-optical path instruments during long-term use, ensuring the reliability and consistency of color measurement data.

2.3 Intelligent Calibration System, Enhancing Long-Term Stability

The HSCD-860 is equipped with a dedicated calibration base, using zirconium material with a Mohs hardness of 9 as the calibration white board. Known as “artificial diamond”, this material has hardness and stability comparable to diamonds, which can avoid surface scratches and discoloration due to changes in temperature and humidity. Compared with the ordinary industrial ceramics or plastic white boards used by similar products, the zirconium reference white board has significantly improved durability and stability. The instrument supports intelligent automatic calibration, no need for frequent manual operation. Placing it on the calibration base can complete comprehensive calibration according to its own state and environmental factors, ensuring that the color measurement instrument is in a stable working state for a long time.

3. Core Characteristics of HSCD-860 Color Measurement Instrument

3.1 High Precision and Consistency, Laying the Foundation for Detection

As a high-precision color measurement instrument, the HSCD-860 performs excellently in core performance indicators. Its measurement repeatability accuracy reaches dEab≤0.03, inter-instrument difference ≤0.3dEab. It uses BCRA series standard color tiles for color transmission and color value traceability to ensure the consistency of measurement data among multiple instruments. The display accuracy is as high as 0.01, which can realize the precise quantification of color data and provide a reliable basis for product quality control.

3.2 Multi-Aperture and Multi-Parameter, Adapting to Diverse Needs

To meet the measurement needs of samples of different sizes, the instrument supports three measurement aperture options, including Φ8mm, Φ11mm+Φ4mm, Φ6mm+3mm, which can be flexibly applied to different test scenarios such as micro-samples and large-area samples. In terms of measurement parameters, the HSCD-860 covers more than 30 measurement indicators such as spectral reflectance, CIE-Lab, CIE-LCh, and supports nearly 40 evaluation light sources such as A, B, C, D50, D65, almost covering all color measurement standards in the industry, adapting to the detection needs of multiple industries.

3.3 Intelligence and Convenience, Improving Operation Efficiency

The HSCD-860 has a built-in high-definition camera, which can clearly capture images of the measured area, realize precise positioning of the measurement position, and avoid measurement deviations caused by incorrect area selection. In terms of operational convenience, this color measurement instrument supports connection with WeChat applets and Android, Apple, HarmonyOS mobile APPs. Users can quickly transmit color data, find similar color cards, create personal color databases through mobile terminals, and support cloud data sharing. At the same time, the instrument is equipped with the Windows-based color management software ColorExpert, which includes four functional modules: My Colors, Color Detection, Color Matching System, and Personal Center, realizing complex operations such as color library management, data export, and automatic color matching, adapting to enterprise-level color management needs.
