High-accuracy Measurements

For Full Details Download the PRODUCT CATALOG Using the SERVICE PULLDOWN Above.

Measurement principle 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] 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). *E3-CMOS sensor: Enhanced Eye Emulation C-MOS image sensor

Laser light reflection	Light intensity	Profile measurement

MFL optimizes the laser power for the target [First in its class] 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. *MFL: Multi Flexible Logic

High-accuracy 2D Ernostar lens [New] 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.
