N-BK7, Double-Convex Lenses, Uncoated, 350 nm-2.0 μm, Unmounted — Model BCX10609

Operating wavelength 350 nm-2.0 μm, focal length 40.0 mm, Ø25.4 mm, substrate N-BK7.

Product Description

  • Optical material: N-BK7
  • Operating wavelength: 350 nm-2.0 μm (uncoated)
  • Application: imaging, beam expansion or reduction, convergence

The double-convex lens has a positive focal length and can be used to focus collimated beams or collimate point light sources. Double-convex lenses are widely used in imaging applications, with N-BK7 being the most common lens material, applied in visible and near-infrared fields. LBTEK selects N-BK7 to manufacture various lenses, all of which undergo fine processing and strict quality control. This ensures that LBTEK provides the users with high-quality lens products at reasonable prices.

N-BK7, Double-Convex Lenses, Uncoated, 350 nm-2.0 μm, Unmounted

  • Substrate material: N-BK7
  • Operating wavelength: 350 nm-2.0 μm
  • Application: imaging, beam expansion or reduction

The LBTEK Double-Convex Lenses have a positive focal length and are commonly used in applications such as imaging or beam collimation. LBTEK manufactures double-convex lenses using N-BK7 glass, which is the most commonly used material for high-quality optical components, primarily for visible and near-infrared applications. All circular lenses from LBTEK are pre-installed with standard lens tubes or lens mounting adapters. These mechanical components are engraved with the product model, type, diameter, and focal length for easy identification of lens parameters.
