High-precision white light interferometers for distance and thickness

How to accomplish high precision absolute measurements with white light interferometers
Interferometry has been a technique for measuring distance for over a century. By using the interference of sound, light or electromagnetic waves and analyzing the received superimposed waves, users can extrapolate precise distances. Micro-Epsilon accomplishes this level of high precision distance and thickness measurements with an innovative white light interferometer technology. These sensors can obtain absolute measurement distances without the need for a reference, allowing them to maintain a precision measurement value before and after signal interruption. This is a massive advantage for distance control and profile measurements of moving objects. 

How capacitive sensors shine in industrial environments
Learn how to use capacitive sensors in various measurement tasks and profit from unsurpassed stability and nanometer resolution — also in industrial applications. Capacitive sensors deliver the highest precision even at extreme temperatures and are suitable for operating conditions ranging from ultra-low temperatures or ultra-high vacuum to dusty industrial environments or clean room applications. Industry-optimized capacitive sensors achieve peak performance in harsh industrial applications and measure with the highest precision.

Submicron precise displacement and thickness measurements on all types of targets
A relatively new technique is the confocal chromatic technology, which is suitable for submicron displacement measurement and even one-sided thickness measurement of transparent materials. This non-contact, wear-free method offers a high measurement rate and high accuracies required in today's industrial plants. In particular, they are used where laser triangulation sensors provide poor results, such as in confined spaces or when highly reflective surfaces or transparent objects need to be measured. Discover the possibilities of the confocal chromatic measurement technology. Confocal systems are ideal feedback devices for both automated processes and quality control inspection systems in a wide range of industries.
