Lighting inspection software

This packaged software is for lighting inspections of OLED/LCD displays which detects point defects and uneven brightness (MURA).

The features

  • You can choose for your use "point defect inspection" or "MURA inspection".
  • You can easily build up inspection environments with sensor devices (2D luminance colorimeter/camera for point defect inspection), a signal generator and this packaged software.
  • You can build up highly flexible inspection environments by writing scripts which are text sequences including measuring orders and measuring conditions.

Sheet pinhole inspection system

The system evaluates pinholes on a long-length sheet, in high speed and high precision.
Characteristics The large image data (about 37 million pixels per second) which multiplies 7,400 pixels by 5,000 lines, is processed at high speed by parallelizing photographing and image signal processing.
Inspection items Detection of pinholes, diameter of a pinhole, area of a pinhole, position coordinate of a pinhole, periodic pitch of pinholes
Inspection target ・Separator for a secondary battery
・Insulation sheet
・Inspection of a hole shape for a perforated film
・Defect detection for a film sheet and a metallic thin film
Basic specification ・Line scan camera: 3 cameras, high-resolution 7,400 pixels
・Measuring resolution of pinhole diameter: 5um
・Minimum diameter size of detected pinhole: 10 um
・Measuring speed: 60 seconds for a sample size, 100 mm×1,200 mm
・White LED
