On-Line Color Measurement of Metallic Surfaces

The SpectraProbe® S/8 provides non-contact, on-line color measurement of metallic coatings and highly specular product. It offers unparalleled accuracy and performance for real-time, continuous color measurement and is ideal for the on-line measurement of coated glass. Use it to continuously measure the reflected color uniformity of metallic surfaces during production for process control, quality control and to keep process records for ISO documentation. The SpectraProbe S/8 is designed for high throughput and for use in harsh production environments. Measurements agree closely with laboratory diffuse/8° geometry instruments.

The system consists of a spectrophotometer sensor, a wall-mounted support unit and host software. The sensor is supplied with a specially designed mounting system for fixed point or traversing color measurement. The computer-controlled traversing rail allows the sensor to be easily positioned over the line at any desired location or be used to continuously traverse the sensor over the line. The mounting systems can also provide automatic calibration and emergency retraction from the line.
