Fresnel Technologies’ polymer aspheric lenses are ideally suited for prototyping and development, as well as incorporation into production systems. Aspheres, which do not exhibit spherical aberration, are excellent optics for such diverse uses as condenser lenses, LED collimators, imaging, focusing for digital detection—and more.
Our polymer aspheres fit standard ½” and 1” lens mounts, are designed for use at conjugates of infinity and the focal length, have a relatively narrow field of view, and can be purchased uncoated or with broadband visible or near-infrared antireflection (AR) coatings. Custom coatings for specific wavelengths or ranges are available.
Below is an overview of our stock polymer aspheres. Download the full polymer aspheres list for more information about lenses for visible, near-infrared, and ultraviolet light applications.
Naming Key Example:
ASP [asphere] - PCX [plano-convex] - 0.5 [inch mount size] - 0.5P [inch focal length, positive] -PMMA [material] (eg. ASP-PCX-0.5-0.5P-PMMA); DCX = double-convex
Mounting dimensions for PCX lenses:
OD: Outer diameter
CA: Clear aperture
CT: Center thickness
ET: Edge thickness
EFL: Effective focal length
BFL: Back focal length
