Optical Thin Films

INO specialists work to client specifications to provide custom reflectors, dichroic filters, and antireflection coatings operating in a wide range of wavelengths, from mid to far-infrared (3 µm to 50 µm).

Our system for depositing thin film facilitates in situ process control and boasts a high continuous evaporation capacity, which makes it possible to process many stacks.

Our expertise:

  • Design of optical thin film stacks

  • Deposition of optical thin films

  • Fabrication of reflectors

  • Fabrication of dichroic filters

  • Deposition of specific antireflection coatings

  • Characterization of thin films

Our strength: Outstanding design flexibility

Our innovative approach allows us to develop the ideal solution for each client.

Fields of application:

Our optical components can be integrated into systems used in a variety of fields:

  • Astronomy

  • Aerospace

  • Aeronautics

  • Remote sensing

  • Night vision systems


The benefits that come with our solutions:

  • Extensive expertise in selecting optical materials

  • A planetary system capable of depositing thin films on substrates diameter up to 8 in.

  • Safety procedures and equipment for handling, evaporating, and storing toxic IR materials

  • Thin films that meet specific needs, including resistance to cryogenic temperatures, abrasion, and high radiant flux
