Non-contact meausurement with laser laser sensors and machine vision

The Measurement Technology Group is a consortium of companies who offer precision non-contact laser based measurement and inspection systems for industry and research. Our member companies both integrate and sell laser distance sensors from short range, high precision units, to long range sensors capable of measuring distances up to 500 meters.

Non-contact measurement techniques using laser based gauging have many advantages over the traditional contact gauging methods, like calipers, hand-held micrometers, and touch probes:

No surface damage, such as scratches or dents
Measurement repeatability is generally improved because you no longer rely on "user feel" operating the measurement device
Properties of soft materials, such as thickness, cannot be physically changed with a laser gauge, like it can with a hand-held micrometer
Non-contact gauges do not physically "wear", thus requiring less maintenance
Non-contact gauges can be readily automated
Non-contact gauges are ideal for integrating into data acquisition systems

Laser Displacement Sensors

A Laser Displacement Sensor is ideal for non-contact precision distance measurement and thickness measurement, and surface profiling. It is common to integrate a laser displacement sensor into in-process thickness measurement applications.

Laser Distance

Laser Thickness

We offer short range laser triangulation sensors with precise measurement ranges as small as 2 mm and long range laser distance sensors that can measure from 0.05-500 meters with mm accuracy.
