High-speed LED Spectrometer LE series

Inline evaluation system for optical characteristics of LED synchronized with control signal in production line. LE-5400 provides the optical characteristics data which are required for quality control such as OK/NG judgement and LED binning.

Product

Features
  • Synchronized with control signal in production line
  • Flexible/various measurement system with optical fiber
  • High speed test – short exposure time (Min. 2ms/ LE-5400)
  • High speed measuring cycle -test/calculation/evaluation  (Half a time compared with conventional model)
