Non-Contact Color Spectrophotometer - Online Color Sensor
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.
Product Detail Diagram
This non contact spectrophotometer is built for industrial-grade performance and easy integration into automated lines. The diagram below highlights the key components and hardware features:
- Display Screen
Shows live L*, a*, b* color data for visual confirmation during production. - Interface and Power Switch
Includes USB-C, Ethernet, and industrial multi-pin connectors to support data transfer and connection to control systems. - Installing Caliber Plates / Testing Ports
Interchangeable testing ports allow flexible use with different materials and measurement requirements. - Fixed Screw Interface
Ensures the online spectrophotometer is securely mounted for stable and accurate readings. - Online Color Quality Control
Multiple non contact spectrophotometers can be deployed across the production line to provide comprehensive, multi-point color monitoring. - Non-Contact Measurement
The device operates at a 5 mm distance from the surface, avoiding contact with sensitive materials and reducing wear, contamination, or distortion risks.
