CF Flanged Exotic Lens Viewports

Features of CF Flanged Exotic Lens Viewports

  • Constructed using premium materials that meet UHV standards.
  • Designed for compatibility with vacuum systems that achieve UHV levels.
  • Equipped with fully annealed copper gaskets to minimize induced strain during operation.
  • For processes that may deposit materials, we highly recommend using a viewport shutter, as deposits can harm the lens and compromise its optical performance.

FAQ

Sputtering targets are materials used in thin-film deposition processes to create coatings on substrates. They are used in industries like semiconductors, optics, photovoltaics, and electronics.

Evaporation materials are used in Physical Vapor Deposition (PVD) processes, where materials are heated and evaporated to form a thin film on a substrate. These are critical for applications in optics, wear protection, and decorative coatings.

Boat crucibles are used as containers for evaporation materials during PVD processes. They help to uniformly evaporate materials onto the substrate for thin film formation.

Sputtering uses energetic particles to eject material from a target, while evaporation involves heating a material until it vaporizes and deposits on a substrate. Both are common methods in Physical Vapor Deposition (PVD) for creating thin films.

Consider the material composition, purity, target size, and application-specific requirements such as the thickness and uniformity of the film.

Yes, we offer customized sputtering targets, evaporation materials, and crucibles to meet specific customer requirements for size, material composition, and purity.

Yes, we can assist in selecting the most suitable material based on your application, whether it’s for optical coatings, semiconductor fabrication, or decorative finishes.

Yes, we offer both bulk and small quantities of sputtering targets, evaporation materials, and spherical powders to support research, prototyping, and development projects.
