Molded Aspheric Lenses ensure the consistency and low cost of lenses in mass production through the molding process. The characteristics of aspheric lenses enable the products to better correct spherical aberration and improve the quality of the focused spot.
For monochromatic light, spherical aberration is often the main factor that limits the performance of a single spherical lens to achieve diffraction limit when focusing or collimating. Therefore, aspheric lenses are often suitable single optical elements for use in many applications. They are often used for collimating the output light of optical fibers or laser diodes, fiber coupling, spatial filtering, and imaging the beam on the detector. Low numerical aperture aspheric lenses are designed to maintain the shape of the beam, while high numerical aperture aspheric lenses can collect all available light sources to maintain beam power at long distances. Molded aspheric lenses are ideal for a wide range of applications, including aiming systems, barcode scanners, laser diode to fiber coupling, optical data storage, or biomedical lasers.
HP-LENS provides customized products of molded glass aspheric lenses. The material is heavy lanthanum flint glass with low melting point and high refractive index. The molding process ensures high quality and reasonable price.
