Features

Achieves bi-directional angled illumination

The LNIS series is a completely new concept product that was developed to detect "moving-direction scratches," which were difficult to detect with conventional line sensor lights.

Difference between bi-directional angled illumination and conventional illumination

Other features

  1. Fan-less (Natural air cooling)
  2. Compact design
  3. Emitting surface 100 to 1,000 mm long (can be made in units of 100 mm)

Perfect for moving-direction scratches such as streaks

Imaging of vertical scratches (moving-direction scratches) on film

Emphasizes only the vertical scratch. Even if you increase the output, the background noise and brightness do not increase.

It's difficult to highlight only the vertical scratch. If you increase the output, the background noise and brightness increase but the contrast ratio does not.

Applications

Scratch inspection on transparent film

Example configuration

Achieves bi-directional angled illumination using an original optical design. This is a line sensor light perfect for detecting moving-direction scratches.
