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 used for collimating point sources, the beam should be incident on the flatter surface of the lens; when focusing collimated beams, 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 high transmittance in the visible spectrum. Compared to precision-polished aspheric lenses, molded aspheric condenser lenses provide better production consistency and are suitable for mass production. LBTEK offers uncoated aspheric condenser lenses as well as lenses with two types of anti-reflection coatings: 400 nm–700 nm and 700 nm–1100 nm. All our lenses undergo fine processing and strict quality control, ensuring that LBTEK delivers high-quality optical products at competitive prices.
