Mesu-Optics has the engineering skills to solve complex problems related to fine mechanical and optical components and systems. Whenever possible, solutions are proposed that save time and money. Furthermore Mesu-Optics can build first prototypes, both mechanical and optical, based upon the design and development done for you. Besides this Mesu-Optics builds the well known Mesu mounts and produces parts of glass, Zerodur of keramic which are optical flat, spherical or a-spherical until a diameter of 500mm and have an accuracy of 1/10λ.
