High-accuracy Measurements

KEYENCE laser displacement technology is optimized for 2D.
These unique techniques provide high accuracy measurements.

Measurement principle

2D triangulation method

2D triangulation method

The laser light is enlarged into strips by the cylindrical lens and diffusely reflects on the target object. The reflected light is focused on the E3-CMOS to measure the displacement or profile of the target.

The LJ-G measures any substance E3-CMOS equipped [World's first]

CMOS image sensor

The E3-CMOS image sensor, developed for machine vision, has a 300 times larger dynamic range than a conventional sensors range and a reliable S/N ratio.
This allows measuring objects such as black rubber (with weak reflection) and metals (with strong reflection).

MFL optimizes the laser power for the target [First in its class]

Multi Flexible Logic

The MFL senses the target surface to optimize laser power.
The dynamic range of the E3-CMOS is 300 times larger than the conventional range. The optimized laser power can capture targets in any condition.

High-accuracy 2D Ernostar lens [New]

2D Ernostar lens

The light receiving lens unit is redesigned to capture the reflected laser light in 2D without error.
The Ernostar lens is composed of four lenses that reduce the aberration of the image. Reducing the aberration allows for a more accurate 2D profile.
