Details

The D8 color inspection system is a robust in-line color matching tool for quality control and precise color consistency. The system is designed for challenging industrial applications, such as consumer electronics manufacturing, and it provides lab-quality measurements directly on the manufacturing line. Its non-contact, real-time spectrophotometer performs measurements in less than a second, enabling throughputs of over 500,000 samples per day with zero cross-contamination. The compact design allows color measurement with the specular component included (SCI) or specular component excluded (SCE) using diffuse illumination and an 8° measurement angle.

At the core of the D8 series is the integration of illumination optics and measurement sensors into a compact assembly that fits into small spaces. It has a fully sealed, chemically resistant case with an easily cleaned and replaceable sapphire window, which protects the integrating sphere and internal optics from dust and other contaminants. There are several configurations available depending on your needs, such as ultra-small spot size measurements, combined SCI and SCE, or fiber-less measurement heads for a movable system.

 

Overview

  • Non-Contact – Throughput can be rapidly increased to 500,000+ parts per day without any cross-contamination or damage to delicate parts
  • Compact – The small, diffuse/8° measurement head can be placed in-line just about anywhere on the production line
  • Outputs – Lab-quality reflectance and CIE colorimetric data from 400 – 700 nm for extremely precise color quality
  • Multiple Configurations – Besides the standard version, other models are configured for:
    • Ultra-small spot size measurements
    • SCI and SCE measurements for high gloss parts
    • Ruggedized, movable system for easy in-line integration and operation in harsh environments
