We also machine reflective surfaces in crystal materials such as germanium, zinc sulfide, zinc selenide and silicon. Large parts can be machined to exacting standards using the extremely rigid Precitech Nanoform 350. Utilizing specially designed natural diamond cutting tools, highly reflective mirror surfaces are produced to submicron dimensional tolerances. The machining of interrupted cuts is a non-issue due to the rigidity of the system. These machines allow the scientist, optical designer and engineer to design systems that work in the infrared, visual and ultra-violet wavelengths. Utilizing the ZYGO Interferometric GPI, ZYGO Zegage Plus  Interferometric 3D Profiler, Taylor Hobson Form Talysurf PGI Optics, we can assure the customer of conformance to specification
