Thin-film optical filter

 


1), Material:  Optical materials(plated cut-off membrane) 

   

2),Specification: In accordance with the drawing, you can provide us your

        drawing, or you tell us the main parameters, then we will design the

        drawing and customize this filters for you.

 
3), Precision (the highest): ±2nm; half width of 7nm; cut-off depth: one part

Optical Thin Film Filters are manufactured by Vacuum deposition of Multilayer Dielectric Coatings onto Glass, Semiconductor or Organic substrates. These substrates can add to the functionality of the filter as a result of their absorption characteristics. Such Filters operate in the Ultraviolet, Visible & Infrared regions. The Dielectric materials and the substrates are selected according to the wavelength region of interest together with environmental and operational requirements

Product Description

Thin-film optics is the branch of optics that deals with very thin structured layers of different materials.[1] In order to exhibit thin-film optics, the thickness of the layers of material must be on the order of the wavelengths of visible light (about 500 nm). Layers at this scale can have remarkable reflective properties due to light wave interference and the difference in refractive index between the layers, the air, and the substrate. These effects alter the way the optic reflects and transmits light. This effect, known as thin-film interference, is observable in soap bubbles and oil slicks.

 

More general periodic structures, not limited to planar layers, are known as photonic crystals.

In manufacturing, thin film layers can be achieved through the deposition of one or more thin layers of material onto a substrate (usually glass). This is most often done using a physical vapor deposition process, such as evaporation or sputter deposition, or a chemical process such as chemical vapor deposition.

 

Thin films are used to create optical coatings. Examples include low emissivity panes of glass for houses and cars, anti-reflective coatings on glasses, reflective baffles on car headlights, and for high precision optical filters and mirrors. Another application of these coatings is spatial filtering.
