Double-Convex Lenses, N-BK7, AR Coating: 400 nm-700 nm, Unmounted — Model BCX10612-A

Operating wavelength 400 nm-700 nm, focal length 75.0 mm, Ø25.4 mm, substrate N-BK7.

Product Description

  • Optical material: N-BK7
  • Operating wavelength: 400 nm-700 nm (anti-reflection coating)
  • 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. Additionally, both surfaces of the lens are coated with an anti-reflection coating for 400 nm-700 nm, which helps reduce the lens's reflectance. 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.

Double-Convex Lenses, N-BK7, AR Coating: 400 nm-700 nm, Unmounted

  • Substrate material: N-BK7
  • Operating wavelength: 400 nm-700 nm (anti-reflection coating)
  • Application: Imaging, beam expansion or reduction, focusing

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.
