The confocalDT 2465 and 2466 Multipeak controllers with high light intensity

ConfocalDT range of controllers provide distance and thickness measurements on a variety of materials

The confocalDT 2465 single channel controller and the confocalDT 2466 dual channel controller offer extremely high light intensity at high measuring rates up to 30kHz.

The confocal measurement principle is designed for high accuracy, non-contact displacement, distance and position measurement against any surface: solid, transparent, polished mirrored surfaces, low reflective matt surfaces and even liquids. If a surface is transparent, a one-sided thickness measurement can be achieved with inbuilt correction for the material refractive index.

The controllers are suitable for use with all confocal chromatic sensors from Micro-Epsilon. They are extremely light-intensive, which enables good signal stability and therefore stable measurements, even on dark or rough surfaces. Very fast measurements are possible on shiny targets.

The confocalDT 2465 is designed for one measuring channel. With the confocalDT 2466, two measuring channels can be processed via one controller, which offers a price advantage for multi-channel applications. Measurement acquisition is synchronous and can be carried out while exploiting the full measuring rate for both channels.

Quite often, confocal sensors are selected when laser triangulation or other optical sensors are not accurate or stable enough on the surface being measured. In addition, confocal sensors have an extremely small spot diameter, typically a few microns and measure in the vertical plane, so do not suffer from shadowing of the reflected light. This also enables measurement into small bores and holes.
