confocalDT Distance/Thickness Spectrometer
Product Announcement from Micro-Epsilon
confocalDT 2451/2471 are the latest high end controllers of the confocal chromatic measurement technology offered by Micro-Epsilon. The controller achieves measurement rates of 10,000 Hz using a white light LED and 70,000 Hz using a xenon light source due to a very good signal-to-noise ration. Due to a comfortably designed web interface the total sensor configuration can be effected avoiding any additional software. The data output is effected via Ethernet, EtherCAT, RS422 or analog output. The confocalDT 2451/2471 are applied in challenging measurement tasks regarding the distance and thickness measurement.
- The fastest confocal controller available
- Nanometer resolution
- Real time surface compensation with high speed exposure control
- Any target including transparent objects
- Configuration via Web-Interface
- Precison optical pens
- Minature optical pens (90deg siede view option)

The confocal measurement principle
Poly-chromatic white light is focused onto the target surface by a multi-lens optical system. The lenses are arranged such that the white light is dispersed into a monochromatic light by controlled chromatic deviation. A certain distance is assigned to each wavelength by a factory calibration.
Only the wavelength which is exactly focused on the target is used for the measurement. This light reflected from the target surface is passed via a confocal aperture to the receiver which detects and processes the spectral changes.
