GREAT BARRINGTON, N.J., 30 Nov. 2006. Edmund Optics Inc. in Barrington, N.J., is offering Tech Spec precision aspheric lenses that are designed for integration into complex optical assemblies and subassemblies such as night-vision objectives, aircraft head-up displays (HUDs), missile guidance systems, and satellite systems.
One asphere can replace several spherical elements, allowing for more compact and lightweight systems.
Reducing the element count also eliminates losses, allowing more energy to get to the detector and creating more sensitive electro-optical assemblies -- a key consideration in low-light applications such as night vision.
Aspheres can also be used to design well-corrected, high numerical aperture assemblies, creating imaging systems that simultaneously have better resolving power and collect more light.
Featuring low f/numbers (0.75 ¿ 1.5) for optimum light gathering and focusing performance, these lenses are computer optimized to eliminate spherical and minimize higher order aberrations.
Precision machined on state of the art aspheric polishing equipment, the lenses feature a 0.75 micron surface accuracy and low image runout. BBAR coatings to enhance transmission and blackened edges to improve system signal-to-noise are available upon request.
