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]).

▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

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.

Aspheric and Spherical Lenses

Zoom

When collecting a lot of light in a lens, it is required the lens which is short focal length and large diameter. However, when input the parallel light to the spherical lens of such conditions, there is the difference between the focal points of the rays passing through the vicinity of and periphery of the optical axis. This phenomenon is called the spherical aberration of the lens. In case of spherical lens, generally since the exceeding refraction occurs at the periphery area, it causes to be focused in closer point to the lens than the laght beam of the vicinity of the optical axis. Therefore, if the lens shape is designed such as more gentle curvature of the lens away from the center of optical axis, all parallel light incident on the lens will be focused at one point.
