  • Assembly tests

  • Durability tests

In – house production

High quality parts made on high tech machines even if it is about prototyping or series production!

  • Vacuum components

    Among others we manufacture custom made CF flanges, vacuum chambers.

  • Prototype manufacturing

  • Series production of small scale parts

  • Custom made high precision optomechanics

  • Manufacturing process optimization
