basic information
**Principle** Our products can mainly be divided into two types based on their measurement principles. ■ Chromatic Aberration Confocal: Primarily used for surface shape measurement, with main applications including height measurement and surface 3D shape measurement. Utilizing the principle of chromatic aberration confocal, we achieve high-speed, high-precision measurements with a large depth of focus and our excellent optical design technology, allowing for high angular tolerance. ■ Spectral Interferometry: Mainly used for thickness measurement. It enables high-precision measurements at the sub-micron level, leveraging the strengths of spectral interferometry. High-speed measurements necessary for in-situ, monitoring, and inline applications are possible. **Product Lineup** ■ Single Point Sensor There are sensors for shape measurement and thickness measurement. There are also affordable types available for under 1 million yen. ■ Line Sensor Primarily used for shape measurement, it can perform full-area measurements in conjunction with a moving stage. ■ Area Scanner Sensor This type can perform area scans with a 2-axis galvanometer. There are also area scanners that do not require a moving stage and are unaffected by vibrations. They can be used for shape measurement and thickness measurement. *For more details, please refer to the PDF materials or feel free to contact us.*
