3nh YS4580 Grating Spectrophotometer (400-700nm; 10nm)

3nh YS4580 Grating Spectrophotometer (400-700nm; 10nm)

In industrial production environments with strict color uniformity requirements, visual inspection always poses significant risks. Conventional colorimeters using a d/8 spherical structure sometimes face major limitations when measuring rough, textured surfaces or special reflective films, as specular reflection can distort the results. The 3nh YS4580 portable spectrophotometer is the comprehensive solution – a device utilizing the strict 45/0 geometrical optical structure from 3nh, helping businesses digitize colors independently, objectively, and with Master-level precision.

Overview of the 3nh YS4580 Spectrophotometer

The 3nh YS4580 is a flagship, premium portable spectrophotometer thoroughly researched by the 3nh brand to optimize mobile inspection capabilities in workshops and warehouses while ensuring reliability equivalent to a laboratory benchtop meter. The device adopts the international standard 45/0 optical geometry structure (45-degree circular uniform illumination and 0-degree vertical reception), fully and strictly meeting the demanding regulations of CIE No.15 and ISO 5-4.

The power that positions the YS4580 as a leader in color inspection for coatings, printing, and traffic materials lies in its concave grating spectrophotometry technology combined with a high-resolution dual-path CMOS matrix sensor system. The device smoothly segments visible light energy from the 400 nm to 700 nm wavelength range with an ultra-small 10nm interval, delivering excellent repeatability in quantitative color results.

Key Features of the 3nh YS4580

💡 Standard 45/0 Optical Geometry – The Ultimate Solution to Gloss Errors

The most valuable highlight of the YS4580 is its strictly designed 45/0 optical structure. By illuminating at a 45-degree angle and receiving the signal at a 0-degree angle, the device completely eliminates specular reflections from surface gloss. This allows the machine to precisely measure the core, intrinsic color of the material, perfectly simulating the natural viewing angle of the human eye when evaluating product appearance. It is exceptionally optimized for matte textured surfaces, textiles, or powder coatings.

💡 Ultra-Fine Spectral Analysis Capacity (400-700nm; 10nm Interval)

Featuring a fine 10nm wavelength interval across the entire visible light spectrum, the 3nh YS4580 is capable of detailed analysis of the spectral reflectance curves of complex molecular color particles (including special Spot colors – Pantone). This spectral analysis technology provides absolute control over metamerism (a phenomenon where colors look identical under workshop lights but mismatch when brought into natural daylight).

💡 Integrated UV Light Source – Standard Measurement for Fluorescent Materials

Unlike conventional models, the YS4580 integrates an independent UV light source to accurately activate and analyze optical brighteners and fluorescent whitening agents commonly found in premium printing paper, textiles, or reflective sign films. This feature ensures that white color data or bright color bands remain highly accurate under all inspection light sources.

💡 Standard Flat Measuring Aperture Design and Precise Locating

The YS4580 comes equipped with a standard flat measuring aperture (typically an 8mm diameter configuration), which is the most common size suitable for the vast majority of industrial production samples. The flat measuring head allows the device to fit completely flush against the large flat surfaces of products, eliminating external stray light interference. Combined with a clear illuminated locating indicator, technicians can easily align the measurement target point with precision.

💡 Comprehensive Color Spaces and Ultra-Fast Pass/Fail Evaluation

With a single press of a button taking less than 1.5 seconds, the sharp industrial graphic display of the YS4580 immediately provides:

• Complete international color space coordinate systems: CIE Lab, XYZ, Yxy, LCh, RGB…
• The most advanced color difference formulas: Delta Eab, Delta E00, Delta Ecmc, Delta E94.
• Intelligent warning mode: Automatically compares the measured sample with the standard sample and instantly displays “Pass” or “Fail” based on the preset tolerance range, helping factory workers quickly screen out defective parts directly on the production line.

💡 Advanced PC Software Connection for Data Management

Via a high-speed USB port or wireless Bluetooth connection, the YS4580 easily synchronizes data with professional color management software on computers. The system supports businesses in storing tens of thousands of standard samples, managing electronic color card libraries, tracking color variation trend charts of production batches, and automatically exporting professional quality inspection report files in PDF/Excel formats to send to major partners.

Practical Applications of the 3nh YS4580

Thanks to its distinctive 45/0 geometry and ultra-sensitive 10nm fine spectral scanning range, the 3nh YS4580 portable spectrophotometer is a core device in the following fields:

• Printing & Paper Packaging Industry: Inspecting color deviation of printing ink on paper boxes, flat corrugated cartons, and embossed decal labels, ensuring brand identity logo colors match actual visual perception.
• Traffic Sign & Reflective Film Benchmarking: Measuring the retroreflective indices and color coordinates of traffic reflective films and road signs according to strict national technical standards.
• Paint & Thin-Film Coating Industry: Measuring and inspecting color deviation of powder coatings, wall paints, and protective coatings on mechanical components, metal furniture, and architectural wood with slight matte surfaces.
• Plastics & Rubber Processing Industry: Controlling the color uniformity of incoming plastic granules, plastic preforms, and the surfaces of standard flat anti-fingerprint molded plastic products.
