Features

Illuminance of 678,000 lx using forced air (fan)

This is a high-output (fan-equipped) type of the LNIS series, developed to detect moving-direction scratches such as streaks. It meets the needs of customers who require even brighter lights.

Comparison between the LNIS and LNIS-FN

Other features

  1. Emitting surface 100 to 1,500 mm long (can be made in units of 100 mm)
  2. Due to the constant-current drive system, the emitting
    surface has uniformity higher than the LNIS series.

Avoid trouble with error detection

①Error detection for cooling fans

An error is detected should a fault occur, such as insufficient speed or a stop in the cooling fans.

②Error detection for the LEDs

Detects dead LEDs due to an open in the Light Unit circuit or a shorted LED.

Error detection is a function included with the PSCC series,the recommended Control Units.

Applications

Scratch inspection on plate glass

Example configuration

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