Optical Fabrication Capabilities

  • Planos: Flat optics include a range of optical components with at least one nominally flat surface.
  • Spheres: Rotationally symmetric optics whose shape corresponds to the section of a spherical surface. Made with a particular radius or curvature.
  • Aspheres: A lens whose surface profiles are not portions of a sphere or cylinder.
  • Freeforms: An optical component that is not translationally or rotationally symmetric.

Coating Capabilities


Coating Technologies

  • Electron Bombardment is capable of vaporizing difficult-to-vaporize materials and producing hard durable films.
  • Plasma Ion-Assisted Bombardment (PIAD) is applied at low temperatures to sensitive substrates while providing durability to heat and humidity.
  • High Laser Damage Threshold Coatings – UV to Midwave
  • Ion Beam Sputtering (IBS) results in thin films with an extremely high laser damage threshold, durability, and density. When the only option is extreme performance, this method is a great choice.
  • Magnatron Sputtering (MSP) is a plasma-based deposition method that accelerates energetic ions toward a target. Atoms are expelled (or sputtered) off the surface when the ions hit the target. These atoms move in the direction of the substrate and combine with the developing film.
