Real-time color measurement without touching the surface
This non contact spectrophotometer is designed for continuous, high-precision color monitoring in production environments. It uses a 45/0 optical geometry (45° circular illumination and 0° viewing angle) to accurately measure surface color without direct contact.
The built-in automatic calibration system eliminates manual adjustment, maintaining consistent performance over time. It is ideal for online color quality control of wet films, coatings, and other sensitive materials.
Key Features
- Suitable for inline color inspection in real-time processes
- Non-contact measurement distance: 5 mm
- Aperture size: 21 mm
- Repeatability: dE*ab ≤ 0.02
- Inter-station variation: dE*ab ≤ 0.25
This online spectrophotometer helps ensure uniform color across batches while reducing downtime and human error.
Application Scenarios
The non contact spectrophotometer is engineered for seamless integration into automated production lines across a wide range of industries:
- Anodization
The online spectrophotometer monitors surface color during the anodizing process to maintain consistent aluminum finishes. - Coating
During wet paint application, the non contact spectrophotometer ensures even color coverage before curing or drying. - Papermaking
Enables high-speed paper color monitoring without disrupting production, helping maintain quality in real time. - Automotive Spraying Line
Detects paint variation on car bodies directly on the spray line, reducing color mismatches with automated online spectrophotometer support. - Textile Production Line
Tracks fabric color consistency during dyeing and finishing, ensuring accurate color from start to finish. - Plastic Production Line
Provides inline color control for films, sheets, and molded parts. The non contact spectrophotometer continuously checks product color during extrusion and forming.
