3D-optics

Geometrically challenging substrates such as ball lenses, tubes, domes, special prisms, gratings, nozzles and many more items cannot be coated by common coating techniques because shadowing effects and thickness non-uniformity will occur here.

With ALD (Atomic Layer Deposition) LASEROPTIK can offer highly conformal multilayer coatings on complex 3D-substrates.

Typically, anti-reflection coatings are offered in the range from UV towards 1550 nm. HR coatings are more suitable for UV applications due to economic coating thickness limitations. In addition, protective and passivating coatings are offered on a variety of materials.
