Brief: Discover the CaF2 Spherical Glass Lens 12.7mm UV Fused Silica Lens with a negative focal length. This plano-concave (PCV) lens diverges collimated beams, ideal for image reduction and light spreading. Perfect for precision optical applications.
Related Product Features:
  • Plano-concave (PCV) lens with one flat and one inward curved surface for beam divergence.
  • Negative focal length for spreading light or reducing images.
  • Available in UV-fused silica, calcium fluoride, and other high-quality materials.
  • Surface flatness N<3(0.5)@632.8nm for superior optical performance.
  • Diameter tolerance of +0/-0.2mm ensures precise fit and alignment.
  • Clear aperture >90% maximizes light transmission efficiency.
  • Optional anti-reflective coatings to minimize surface reflections.
  • Customizable designs including optical, mechanical, and coating specifications.
Fragen und Antworten:
  • What is the primary use of the CaF2 Spherical Glass Lens?
    The lens is primarily used for diverging collimated beams, making it ideal for applications like image reduction or spreading light in optical systems.
  • What materials are available for the plano-concave lenses?
    The lenses are available in materials such as N-BK7, UV-fused silica, calcium fluoride (CaF2), zinc selenide, and others, catering to diverse optical needs.
  • Are there coating options available for these lenses?
    Yes, various anti-reflective coatings are available, including single-layer MgF2, multi-layer AR coatings, broadband AR coatings, and dual-wavelength AR coatings to reduce reflections.
  • Can the lenses be mounted?
    Yes, Star Optic offers both fixed and adjustable mounting options for these plano-concave lenses to suit different application requirements.
