Confocal sensors: high-precision measurements on curved surfaces

The new confocalDT IFS2407-3 series is characterised by a numerical aperture (NA) of 0.43, which allows the measurement object to be tilted by +/-30 degrees. This means the sensors are particularly well suited to measurements on curved and reflecting surfaces. The sensors also provide a measuring range of 3mm and a large offset distance of 28mm. Due to their outstanding performance features, the sensors are suitable for geometrical inspection tasks in coordinate measuring machines, delivering stable, high-precision measurement on target objects such as gear wheels and external threads.

The confocalDT IFS2404 / 90-2 confocal sensor measures distance, position and thickness with a measuring range of 2mm and a resolution of 0.040um. Due to its special design, the sensor is suitable for mounting in small installation spaces. The 90 degree lens enables the installation depth to be reduced. An excellent price-performance ratio makes the sensor suitable for high-volume, OEM applications.

With the confocalDT series, Micro-Epsilon offers excellent dynamics and precision. In addition to the standard portfolio, sensors can be adapted with different mounting options, modified designs and individual cable lengths. Used in combination with the confocalDT controllers from Micro-Epsilon, measuring rates up to 70kHz can be achieved.
