Double-Convex Lenses, UVFS, AR coating: 245 nm-400 nm — Model MBCX20613-UV
Operating wavelength 245 nm-400 nm, focal length 50.0 mm, Ø25.4 mm, substrate UV Fused Silica.
Product Description
- Optical material: UV fused silica
- Operating wavelength: 245 nm-400 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 245 nm-400 nm, which helps reduce the lens's reflectance. 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.
