L.E.T. Optomechanika Praha is an optical company, that since 1993 has been dealing with thin film coating, optometry, photolithography, optical components. However, we are able to deliver complete solutions including installation and precise positioning of optical elements.

The company employs 14 people. More than 80% of our production is exported to the EEC mainly to Germany, Switzerland, France, the Netherlands and Belgium.
We deliver for a long time measuring discs not only to companies in the Czech Republic, but also in Germany and Belgium. We work with our customers on the development and optimization of special calibration plates for the calibration of measuring devices, which are then exclusively produced for them.

The production program also includes calibration scales and counting chambers McMaster and Cyrus for companies and institutions in the Czech Republic and France. Furthermore, we make photolithographic motifs into thin layers (dielectric filters, metal layers, conductive layers) and on glass and sapphire substrates or on crystals. An integral part of our production is the production of optical components and assembly of opto-mechanical devices.

We work closely with the Academy of Science and the Faculty of Mathematics and Physics of the Charles University in Prague.

We have successfully participated in the chipCAT project (
This project dealt with the design of thin-film nanocatalysts for chip fuel cell technology. The project was a collaboration with:
