SuperLIX

The SuperLIX is an ultra-high-precision laser interferometer capable of resolving thermal expansion coefficients down to 1×10⁻⁸/K. It is the definitive instrument for zero- and negative-expansion materials, semiconductor lithography components and other applications demanding world-class measurement accuracy.

Overview

SuperLIX is an ultra-high-precision laser interferometric thermal expansion system designed for materials where even minute dimensional changes matter. It enables reliable expansion analysis down to the 10−8/K level for advanced R&D and high-accuracy quality control.

SuperLIX is built for thermal expansion measurement of ultra-low-expansion materials, using a dual-path Michelson laser interferometry approach for very high displacement resolution. The system targets applications where conventional dilatometry is often not sufficient, including precision ceramics, specialty metals, and components used in high-accuracy manufacturing systems.

By combining optical displacement measurement, vibration-disturbance suppression, and stable thermal control, SuperLIX supports repeatable measurements in demanding environments. The platform is especially suitable for development and qualification of zero-expansion and negative-expansion material systems.
