Aspheric Condenser Lens 12mm Diameter 8.5mm Focal Length

AGL-12-8.5P

Aspheric condenser lens is a single lens for collection and condensing, which the radius of curvature of one side is changed according to the height from the optical axis to minimize spherical aberration. The other side is plano or convex.
◦These lenses can condense light at a short focal length superior to what can be achieved with spherical lenses.
◦Since these lenses are molded polished from B270-Superwhite, complex shapes that cannot be polished can be easily manufactured.
◦These lenses are designed for the use at infinite conjugate ratios and focal lengths are designed at 587.6nm (yellow helium line [d]).

Guide
  • Please contact our Sales Division for Aspheric Condenser Lenses with anti-reflection coating.
  • B270® is a registered trademark of SCHOTT AG Inc.
Remark -
Attention
  • When the parallel light is incident from the rear (side of plane or large spherical curvature), spherical aberration will not condense into a large point.
  • Aspheric condenser lens is used as an illumination light source. It is not aberration-free for laser focusing.
  • Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
