3nh YL4660 Spectrophotometer and Color Meter

3nh YL4660 Spectrophotometer and Color Meter

In the automotive, motorcycle, premium coatings, and cosmetic packaging manufacturing industries, the utilization of special effect paints such as metallic or pearlescent finishes has become increasingly widespread. The defining characteristic of these coatings is that their color and sparkle texture shift depending on the viewing and illumination angles. Conventional fixed single-angle color measurement instruments are entirely helpless when facing these materials. The 3nh YL4660 multi-angle spectrophotometer stands as the ultimate advanced solution—precisely isolating and quantifying color across multiple angles in strict compliance with the most rigorous global standards.

Overview of the 3nh YL4660 Spectrophotometer

The 3nh YL4660 is a premium portable multi-angle spectrophotometer developed by 3nh. The instrument flawlessly replicates how the human eye observes an effect-coated surface by integrating a multi-directional light source and sensor system.

During a measurement cycle, the device illuminates the target and captures reflection signals at multiple standard tilt angles relative to the specular reflection angle. Powered by advanced diffraction grating technology and a high-resolution CMOS matrix sensor array, the YL4660 conducts an in-depth analysis of the spectral range from 400nm to 700nm, delivering a comprehensive set of colorimetric data for surfaces with complex color flop behavior.

Key Features of the 3nh YL4660

💡 Simultaneous Multi-Angle Measurement – Clear Vision of All Color Flop Effects

The core engineering that drives the power of the 3nh YL4660 is its capability to measure color at multiple angles simultaneously with a single click. This multi-angle data acquisition enables QC engineers to precisely control color shifting, sparkle intensity, and coarseness of aluminum flakes or pearlescent pigments blended within the coating film when orientation changes.

💡 Diffraction Grating Spectrophotometry and Dual-Path CMOS Sensor

The device implements a premium optical diffraction grating light-splitting system paired with an ultra-sensitive CMOS matrix sensor. This technology ensures the instrument isolates light energy smoothly at individual specific wavelengths, delivering exceptional accuracy, repeatability, and measurement stability while completely eliminating environmental stray light interference.

💡 Intuitive Graphical Display and Ultra-Fast Pass/Fail Quality Auditing

Featuring an expansive, sharp industrial touchscreen interface, the YL4660 delivers a streamlined user experience:

• Intuitively displays spectral reflectance curves across all measured angles simultaneously.
• Provides comprehensive International Color Spaces: CIE Lab, XYZ, Yxy, LCh… alongside advanced color difference formulas like Delta Eab, Delta E00, and Delta E*cmc.
• The smart warning mode automatically displays a clear Pass or Fail result based on pre-set tolerances, enabling rapid field identification of non-compliant parts directly on assembly lines.

💡 Ergonomic Form Factor and Unlimited Smart Connectivity

The instrument features a robust, pistol-grip form factor with optimized surface contact points to prevent slippage, ensuring the probe makes a tight, flush seal against complex curved automotive body panels. The YL4660 supports Bluetooth and USB connectivity, synchronizing effortlessly with in-depth PC color management software to track international color card libraries and automatically export professional quality control documentation (QC Reports).
