Description
The optical pen or optical probe is the measuring head of the sensor. It is connected to the controller thanks to an optical fiber. The various optical pens are defined by different measuring ranges and resolutions. A single controller can work with several optical pens. Chromatic Confocal technology is the optimized solution to produce different types of high-accuracy measurements. Each optical pen offers a working distance, a measurement dynamics, a spot size on the target as well as an angular opening of the light beam, making it unique.
Optical pens perform without contact with the target. 
They cannot alter, nor deform this target when measuring it. Besides, with the right choice of measurement dynamics, there is no need to refocus the light beam on the target for a series of measurement on identical objects.
