Confocal Distance / Thickness Measurement - By Micro-Epsilon

Supplier: Bestech Australia playlist_addCompare

Designed for low range distance and one-sided thickness measurements, the series 2401 confocal distance sensors from Micro-Epsilon will be useful to have.

Price Guide (Inc GST): POA

The distance sensor can measure on shiny and transparent objects, and is ideal for precision measurement against diffuse and reflective materials, eg. film, liquid, glass, metal, polymer, etc.

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.

Performance and special features

This unique measuring principle enables displacements and distances to be measured with the highest precision. Both diffuse and reflective surfaces can be measured in liquid or solid state. With transparent materials a one sided thickness measurement can be accomplished along with the distance measurement. Since the emitter and receiver are arranged in one axis, shadowing is avoided.
