Aspheres are optical lens elements with at least one non-flat, non-spherical surface. There are a number of benefits associated with using an asphere over a spherical lens element such as the elimination of spherical aberration, superior focusing ability for smaller spot sizes and reduced blur, and better light collection. Aspheres are commonly used as a lighter and smaller alternative to using a series of spherical components to accomplish the same result in a lens assembly. Edmund Optics currently offers a wide range of different aspheres and possesses extensive asphere design, manufacturing, and metrology expertise. Manufacturing thousands of precision aspheres each month Edmund Optics holds a large inventory of standard and high precision lenses for immediate delivery and extends its offerings continuously reflecting the needs of markets and customers.
The TECHSPEC® Double-Sided Aspheric Lenses feature high numerical apertures, diameter options from 10 mm to 500 mm, and are excellent options ideal for light collection or for 1:1 imaging applications. The double-convex or bi-convex design is used to reduce the number of optical elements in the optical system and consolidate the system space and weight for superior performance.
TECHSPEC® Near-Infrared (NIR) Precision Aspheric Lenses are optimized to eliminate spherical aberration in the near-infrared spectrum. These aspheric lenses are manufactured from S-LAH64 or N-BK7 substrates and polished through a computer numerical controlled (CNC) machining process to achieve high-precision performance. While the uncoated substrate option is designed for 780 nm, other coatings options are available for 350-700 nm, 600-1.050 nm, and 900-1.700 nm.
