Double-Convex Lenses, UVFS, Uncoated: 200 nm-2.1 μm, Unmounted — Model BCX20613
Operating wavelength 200 nm-2.1 μm, focal length 50.0 mm, Ø25.4 mm, substrate UV Fused Silica.
Product Description
- Optical material: UV fused silica
- Operating wavelength: 200 nm-2.1 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. LBTEK manufactures various lenses using UV fused silica, which exhibits high transmittance from the ultraviolet to near-infrared band, making it an ideal material for lenses operating in this band. Our lenses 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, UVFS, Uncoated: 200 nm-2.1 μm, Unmounted
- Substrate material: UV fused silica
- Operating wavelength: 200 nm-2.1 μm (uncoated)
- Application: imaging, beam expansion or reduction, convergence
The LBTEK Double-Convex Lenses have a negative focal length and are commonly used in applications such as imaging or beam collimation. UV-grade fused silica exhibits high transmittance in the deep ultraviolet range and produces almost no laser-induced fluorescence, making it suitable for applications spanning from ultraviolet to near-infrared band. All circular lenses from LBTEK can be mounted in LBTEK standard lens tubes, fixed lens mounts, and various coaxial mounting plates. Customers can choose the optimal mounting solution for different application scenarios.
