Product Description

l Optical Element Material: D-ZK3/D-ZLAF52LA/D-LAK6

l Larger Numerical Aperture (NA), Lower F-number (f/#)

l Suitable for Focusing, Collimation, and Detection

l Uncoated, Available in Unmounted or Mounted Options

     Compared to conventional spherical lenses, molded aspheric lenses do not introduce spherical aberration into the transmitted wavefront when focusing or collimating a beam. Tuniu utilizes D-ZK3, D-ZLAF52LA, and D-LAK6 glass to manufacture molded aspheric lenses in various sizes. These three materials have higher refractive indices than B270 glass, resulting in molded aspheric lenses with larger numerical apertures (NA) and lower f-numbers (f/#). 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 surface with greater curvature. Compared to precision-polished aspheric lenses, molded aspheric lenses offer advantages such as better production consistency and suitability for mass production. Tuniu provides uncoated molded aspheric lenses with various focal lengths and sizes, available in both unmounted and mounted options. All our lenses undergo fine processing and strict quality control to ensure that Tuniu delivers high-quality lens products at reasonable prices.

Molded Aspheric Lens, D-ZLAF52LA/D-ZK3/D-LAK6, Uncoated, Unmounted

l Optical Element Material: D-ZLAF52LA/D-ZK3/D-LAK6

l Working Wavelength: 290 nm-2400 nm

l Various Diameter and Focal Length Options Available

     Tuniu offers molded aspheric lenses with various diameter and focal length options currently available. The spherical refraction of conventional lenses cannot converge parallel light to a single point, resulting in spherical aberration. In contrast, the surface curvature of aspheric lenses varies continuously from the center to the edge. By adjusting the conic constant and aspheric coefficients, spherical aberration can be minimized to the greatest extent, allowing light rays to converge at a single point, thereby enhancing optical performance.

l Optical Element Material: D-ZLAF52LA/D-ZK3/D-LAK6

l Working Wavelength: 290 nm-2400 nm

l Various Diameter and Focal Length Options Available

l Different Element Sizes Correspond to Different Housing Thread Specifications

     Tuniu offers mounted molded aspheric lenses, currently available in various diameters and focal lengths. Different element sizes correspond to different housing thread specifications, which can be adapted and installed using threaded adapters. The housing of the mounted molded aspheric lens is engraved with a LOGO and product model for easy identification during use. One end of the housing features a groove, allowing for assisted installation with a compatible wrench. The side facing the groove is the side with the larger curvature of the molded aspheric lens.
