3nh YL4560 Non-Contact Spectrophotometer (400-700nm; 10nm)

3nh YL4560 Non-Contact Spectrophotometer (400-700nm; 10nm)

In industrial color quality management processes, utilizing contact-type colorimeters (which require pressing the measuring aperture directly against the surface) often encounters significant obstacles and can even be impossible when dealing with specific material forms. For products such as wet paint, undried printing ink, gel-like chemicals, liquid foods, cream cosmetics, or newly coated mechanical components… pressing a measuring aperture onto the surface would damage the sample structure and contaminate the instrument’s optical chamber. The 3nh YL4560 non-contact spectrophotometer represents a technological revolution—allowing precise remote color measurement and spectral analysis from a distance without touching the product, enabling comprehensive color digitization for all material states.

Overview of the 3nh YL4560 Non-Contact Spectrophotometer

The 3nh YL4560 is an ultra-premium high-end engineering non-contact spectrophotometer developed by the 3nh brand. The device utilizes an internationally standardized 45/0 optical geometric structure (uniform 45-degree circumferential illumination and 0-degree perpendicular signal reception), fully satisfying the strict regulations of CIE No.15 and ISO 5-4 standards.

The exclusive advantage of the YL4560 lies in its smart dynamic measurement capability. A fixed safe distance is constantly maintained between the instrument’s measuring head and the tested product surface. The device utilizes diffraction grating spectral separation technology paired with a high-resolution dual-path CMOS matrix sensor system to extract spectral energy from 400nm to 700nm at a fine 10nm interval, delivering ideally stable measurement results to international laboratory standards.

Outstanding Features of the 3nh YL4560

💡 Non-Contact Measuring Technology – Ultimate Protection for Samples and Equipment

The YL4560 establishes a standard measuring distance from the optical lens to the material surface without any direct contact. This intelligent isolation functionality delivers exceptional benefits:

• Completely eliminates the risk of cross-color contamination between different test samples.
• Prevents wet ink, wet paint films, or sticky chemicals from adhering to, contaminating, or scratching the internal optical lenses.
• Specialized for testing sticky, wet, or loose powder samples that are otherwise difficult to fix in place.

💡 Standard 45/0 Optical Geometry – The Nemesis of Gloss-Induced Errors

The device implements a rigorously engineered 45/0 optical geometric structure. By illuminating the surface at a 45-degree angle and capturing the signal perpendicularly at 0 degrees, the instrument completely eliminates specular reflection interference caused by surface gloss or roughness. This enables the machine to accurately measure the intrinsic core color of materials, perfectly simulating the natural viewing angle of the human eye during product aesthetic evaluations.

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

Featuring a fine 10nm pitch interval across the entire visible light spectrum, the 3nh YL4560 can perform detailed analysis of the spectral reflectance curves of complex molecular pigments (including custom spot colors – Pantone colors). This spectral analysis technology ensures absolute control over metamerism (a phenomenon where colors look identical under shop-floor lighting but exhibit a discrepancy when moved to natural light).

💡 Ultra-Precise Integrated Automatic Distance Sensor

To ensure that non-contact measurements achieve outstanding repeatability, the YL4560 integrates a real-time micro-technology distance measurement sensor. The instrument automatically detects the position, calculates the distance from the lens to the sample, and only triggers the measurement command when the sample sits precisely within the standard optical focal length, completely eliminating variance caused by manual human adjustments.

💡 Visual Target Alignment via Sharp Display Camera Viewfinder

Aligning the measurement center on small, complex details becomes effortless thanks to the integrated real-time camera positioning system that visually displays the target area on the screen. Technicians can monitor and know exactly where the machine is performing its spectral scan to yield the most objective quality control data.

💡 Automation System Integration and International Standard Reporting

The YL4560 supports high-speed industrial data transfer ports and connects seamlessly with professional PC-based color management software. The instrument can be easily integrated onto robotic arms or automated fixtures over conveyor lines to perform real-time online color measurements for products running down the production line, automatically exporting professional quality control reports (QC Reports) in PDF/Excel formats for storage or client submission.
