Optical coating
Numerous precision engineering components have an optical function. Optically active coating systems have the task of providing or optimising the desired functionality. These coatings are often deposited in vacuum processes by different procedures (evaporation, sputtering).
The deposition of optical coating systems pursues different objectives such as:
The reflexion of metallic surfaces and/or the use of interference effects from combined dielectric coating materials are primarily responsible for the effectiveness of an optical surface coating.
Glass, plastic, metal or ceramic in particular are used as a substrate for the components.
The deposition of optical coating systems pursues different objectives such as:
- Enhencement of reflexion
- Improvement of transmission
- Precise definition of reflexion / transmission / absorption
