Universal confocal controller with one and two channels                                                         Product Technology

The confocalDT 2421 and 2422 controllers are used for distance and thickness measurements of diffuse reflecting and specular surfaces. Available as either a single- or a dual-channel version, these confocal chromatic measuring systems offer a low cost solution especially for series applications. The active exposure regulation feature in the CCD array enables accurate, fast surface compensation on changing surfaces.

This controller is compatible with all sensor types of the IFS series covering numerous measurement tasks. The controller is optionally available as a multi-peak version for multi-layer thickness measurements. Using a special calculation function, the confocalDT 2422 dual-channel version evaluates both channels. Measurement acquisition is synchronous and can be carried out while exploiting the full measuring rate for both channels.
