CF Flanged Quartz (Fused Silica) Re-Entrant Viewports

Key Characteristics of CF Flanged Quartz (Fused Silica) Re-Entrant Viewports:

  • Crafted from top-tier materials that meet Ultra-High Vacuum (UHV) specifications.
  • Fully compatible with vacuum systems designed to attain UHV levels.
  • Sealed using fully annealed copper gaskets to mitigate stress and strain.
  • In scenarios where material deposition occurs, the use of a viewport shutter is highly advisable, as deposits can adversely affect the lens’ optical performance and integrity.

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.
