Aspheric Lens D75mm FL60mm Optics Uncoat LED Illumination H-K51 Product Description Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly. The surface profiles of aspheric lenses are not a portion of a sphere or cylinder. Their curvature radius varies with the central axis. Aspheric lenses have unique advantages over spherical lenses. For example, they can improve optical quality, reduce optical components and design costs. They are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, CD players and high-end microscopic instruments. Difference between aspheric lenses & spherical lenses: Aspheric Lenses: Advantages & Disadvantages In a nutshell, aspheric lenses have the following advantages: They provide a thinner profile They are lightweight and comfortable They could be fit into most frames so you have a wide choice of styles They have a more natural and pleasing appearance They don't make your eyes look too big or too small They provide a better peripheral vision by eliminating distortion Processing Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately. Oplens equipped Zygos which work by producing a beam of laser light and transmitting it to the optic under test by way of a very, very accurate lens fitted to the Zygo. This is the key to the instrument's accuracy. As the light passes through this lens, which is not coated, it enables 4% of the light to be reflected back into the Zygo. Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics. It occupies 10,000 square meters of modernized facilities with hundreds of equipments and instruments. More importantly, Oplens owns an excellent team of more than 200 experienced engineers and workers, who provide the best products and service to their both domestic and overseas customers. Oplens (brand owned by SiChuan JUKA Optical Technology) is located in the city of Chengdu, China, which enjoys the reputation of the world optical processing center. Oplens is established during the restructuring of the Processing Department of the Institute of Optics and Electronics, Chinese Academy of Sciences.
