The laser interferometers and related equipment, which earn a top share in Japan, used for the surface configuration of lenses and metals on the order of nanometers.

The de facto standard for optical devices. Our interferometers measure the surfaces of lenses, metals and ceramics on the order of nanometers. Possible to measure any sample materials contact-free as long as they have mirror surfaces. Our pursuit of excellent usability led us to establish high-functional, high performing laser interferometry systems, which include the fringe analysis device which analyzes and quantifies fringe patterns.
