Company information
Unisoku was established in 1974 with the aim of becoming a creator of unique measuring instruments. It is a manufacturer that primarily develops and sells its own ultra-high vacuum scanning probe microscopes (SPM) to universities, public institutions, and private companies and research institutes. Over the years, it has developed and commercialized advanced measuring instruments such as high-speed spectroscopic measurement devices and scanning tunneling microscopes, delivering them to universities and research institutions both domestically and internationally, and its technological content has received high praise from researchers in the field of basic research. In recent years, scanning probe microscopes have significantly improved in performance and multifunctionality, particularly as a means of observing sample surfaces at the atomic level. Their applications are expanding mainly from the field of physics to chemistry and bio-related fields, making them indispensable tools in nanotechnology and nanoscience.
