MEASURING PRINCIPLES

Enhanced 3D optical metrology techniques
Designed as high-performance optical profilers from the outset, some of our systems outperforms all existing optical profilers, combining 3D optical metrology techniques all together.

Fringe projection is ideal for large area measurements, providing high vertical accuracy and repeatability with low system noise.

PORTFOLIO
Technology combinations
Our systems operate with different optical measurement techniques, combined in some of them. Joining these technological benefits, the incorporation of latest technology and the software which operates them, results in a high-level equipment of maximum competitiveness in the market.








Why 4-in-1 Technologies?

With Sensofar’s 4-in-1 approach – as found in the S neox system – a single click in the software switches the system to the best technique for the task at hand. There are 4 measurement techniques found in the S neox sensor head – Ai Focus Variation, Confocal, Interferometry & Spectroscopic Reflectometry– thus each contribute critically to the versatility of the system, help minimize undesirable compromises in the data acquisition, and together provide Sensofar’s class-leading surface measurement performance.
PATENTED TECHNOLOGY
Microdisplay is the key!
Sensofar’s systems utilize a patented microdisplay scanning technology. The microdisplay is based on ferroelectric liquid crystal on silicon (FLCoS) technology, creating a rapidly switching device with no moving parts that makes the scanning of Confocal images fast, reliable and accurate. This, in combination with high-resolution scanning stages and swappable objectives, provides a flexible optical system.

The most popular optical measurement techniques (Confocal, Interferometry, Ai Focus Variation and Spectroscopic Reflectometry), found in most of the systems in the market, enable users to obtain the measurements they need in their surface metrology works.
