Plano-Convex (PCX) Lenses, UV Fused Silica, AR Coating: 350-700nm, Unmounted — Model CX20821-A

Operating wavelength 350 nm-700 nm, focal length 501.8 mm, Ø50.8 mm, substrate UV Fused Silica.

Product Description

  • Optical Material: UV Fused Silica
  • Working Wavelength: 350 nm-700 nm
  • Application: Imaging, Beam Expansion or Reduction, Focusing

LBTEK plano-convex lenses are made from UV-grade fused silica glass, offering better uniformity and a lower coefficient of thermal expansion compared to N-BK7 glass, making them suitable for ultraviolet and near-infrared wavelength ranges. LBTEK plano-convex lenses have a positive focal length and are commonly used in applications such as imaging or beam collimation. LBTEK offers both unmounted and mounted plano-convex lenses, with an operating wavelength range of 350 nm to 700 nm, and available in three element diameters: 12.7 mm, 25.4 mm, and 50.8 mm. The mounted lenses are pre-installed in standard lens tubes, with the product model, type, diameter, and focal length engraved on the tube surface for easy identification of lens parameters. Additionally, LBTEK supports flexible customization of parameter specifications to meet diverse application needs. For more details, please contact LBTEK Technical Support.
