CF Flanged Quartz (Fused Silica) Viewports

Features of CF Flanged Quartz (Fused Silica) Viewports

  • Exceptional Quality Construction
    Our CF flanged quartz viewports are crafted using top-tier materials, ensuring they meet ultra-high vacuum (UHV) standards.
  • UHV Compatibility
    These viewports are designed to work seamlessly with vacuum systems that can achieve UHV levels, making them ideal for high-performance applications.
  • Enhanced Sealing Options
    For optimal performance, the viewports can be sealed with fully annealed copper gaskets, which help minimize induced strain during operation.
  • Protective Shutter Recommendation
    If your process involves material deposition, we highly recommend incorporating a viewport shutter. This additional feature can help prevent deposits from accumulating on the lens, safeguarding its optical 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.

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.
