Aspherical Lens

Aspherical Lens


Aspheric 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 sides are plano or convex.
These lenses can condense lights at a short focal length that cannot be done with spherical lenses.
