Compared to conventional spherical lenses, aspheric condenser lenses feature a larger numerical aperture (NA) and lower f-number (f/#). These condensers are suitable for collimating broadband light sources, LEDs, or other illumination scenarios requiring high efficiency. To ensure optimal performance, when collimating a point source, the beam should be incident on the flatter surface of the lens; when focusing a collimated beam, the beam should be incident on the more curved surface. LBTEK manufactures various aspheric condenser lenses using B270 glass, a high-quality glass developed by Schott with excellent surface flatness and optical performance, offering good transmittance in the visible spectrum. Compared to precision-polished aspheric lenses, molded aspheric condenser lenses offer superior production consistency and are suitable for mass production. LBTEK provides uncoated aspheric condenser lenses as well as lenses with two types of anti-reflection coatings: 400-700 nm and 700-1100 nm. All our lenses undergo fine processing and strict quality control, ensuring that LBTEK delivers high-quality lens products to customers at reasonable prices.
