Precision Optics

Optical coating refers to one or more thin layers of material (metal or dielectric) deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical coating is an antireflection coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and photographic lenses. Another type is the high-reflector coating which can be used to produce mirrors which reflect greater than 99.99% of the light which falls on them. More complex optical coatings exhibit high reflection over some range of wavelengths, and anti-reflection over another range, allowing the production of dichroic thin-film optical filters. High tech applications of optical coating include tele-communication, display, satellite communication, semiconductor laser diode, MEMS, bio-chips and so on. 

Our optical deposition systems (based on e-beam & reactive sputtering technology) is capable of fabricate the most complicated optical coatings based on optical simulation. Parameters regarding layer stacks, layer thickness, layer uniformity, and layer chemical composition are controlled by PLC via user friendly GUI.
