Aspherical Lenses Aspherical lenses are advanced optical components designed to focus or collimate light without the spherical aberration common in simple lenses. By having a non-spherical shape, they efficiently correct for optical distortions, allowing for better image quality and tighter focus of light beams. This makes aspherical lenses invaluable in applications requiring high precision, such as in laser systems, imaging devices, and optical instruments. Their unique design enables compact, lightweight optical assemblies, enhancing performance in a wide range of technological and scientific applications. Types of Aspherical Lenses Asphere Lenses Asphere lenses minimize spherical aberration, enhancing optical performance for sharper imaging and efficient light focusing in compact designs. Precision Polishing Aspherical Lens Precision polishing of aspherical lenses ensures superior optical clarity and accuracy, critical for high-performance imaging and laser applications. IR Asphere Lenses IR asphere lenses optimize infrared light focusing, improving thermal imaging and laser system performance with minimal aberrations. Parabolic Mirrors Parabolic mirrors focus light into parallel beams, eliminating spherical aberration, ideal for telescopes, solar collectors, and high-intensity applications.
Achromatic triplet lenses minimize Seidel aberrations, usually by gluing three lenses together or mounting three lenses in a housing. Suitable for measurement and imaging applications such as projection, photography, fluorescence microscopy, image relay, inspection, spectroscopy, etc. After milling, fine grinding, grinding and polishing, the single lens in the glued lens can reach the optical surface accuracy â?¤0.1 micron, and the surface roughness Raâ?¤0.01 micron. The three lenses are glued to three lenses, and the achromatic triplet lens is glued by using a centering device with a curing device with UV photosensitive adhesive for precision bonding and eccentricity testing.
