Plano-Concave Lens, UVFS, AR coating: 245 nm-400 nm — Model MCC20312-UV

Operating wavelength 245 nm-400 nm, focal length -75.0 mm, Ø12.7 mm, substrate UV Fused Silica.

Product Description

  • Optical Material: UV Fused Silica
  • Application: Imaging, Beam Expansion or Reduction
  • Operating Wavelength: 245 nm-400 nm (AR Coating)

The plano-concave lens has one concave surface and one flat surface, featuring a negative focal length. It is commonly used for beam collimation, increasing (or decreasing) focal length, or expanding (or reducing) images. To minimize spherical aberration, when the incident beam is collimated, it should be directed onto the concave surface of the plano-concave lens. LBTEK chooses Ultraviolet-Grade Fused Silica (UVFS) as the substrate material for lenses because UVFS exhibits high transmittance in the deep ultraviolet spectrum and produces almost no laser-induced fluorescence. Additionally, UV fused silica offers better homogeneity and a lower coefficient of thermal expansion compared to N-BK7. Besides UVFS plano-concave lenses, LBTEK also provides Plano-Concave Lenses made of N-BK7, N-SF11, and calcium fluoride. N-BK7 is the most commonly used material for high-quality optical components, widely applied in visible and near-infrared applications. N-SF11 is characterized by its low Abbe number and high dispersion, while calcium fluoride boasts an extremely high damage threshold and chemical inertness. LBTEK offers uncoated UVFS Plano-Concave Lenses as well as lenses with four types of anti-reflection coatings: 245-400nm, 400-700nm, 700-1100nm, and 1100-1650nm. All our lenses undergo precision machining and strict quality control to ensure that LBTEK delivers high-quality lens products to customers at reasonable prices.

Plano-Concave Lens, UVFS, AR coating: 245 nm-400 nm

  • Substrate Material: UVFS
  • Operating Wavelength: 245 nm-400 nm
  • Application: Imaging, Beam Expansion or Reduction
  • Pre-installed Mechanical Housing

LBTEK Plano-Concave Lenses have a negative focal length and are commonly used for image reduction or beam divergence. Since UVFS has a low Abbe number, LBTEK selects Ultraviolet-Grade Fused Silica as the lens substrate material because UVFS exhibits high transmittance in the deep ultraviolet spectrum and generates almost no laser-induced fluorescence. Additionally, UV fused silica offers better homogeneity and a lower coefficient of thermal expansion compared to N-BK7. All circular lenses from LBTEK come pre-installed with standard lens sleeves or lens mounting adapters. These mechanical components are engraved with product model, type, diameter, and focal length for easy identification of lens parameters by users.
