Product Description
Aspherical lenses
Aspheric lenses are designed to focus or collimate light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents a single spherical lens from achieving diffraction limited performance when focusing or collimating light. Thus, an aspheric lens is often the best single element solution for many applications including collimating the output of a fiber or laser diode, coupling light into a fiber, spatial filtering, or imaging light onto a detector.
Aspherical lenses
The most notable advantage of using an aspherical lens is the reduction in spherical aberration commonly seen in spherical lenses. Spherical aberration occurs when a lens is not capable of focusing all the incident light rays on the exact same point. Any spherical optical surface, even a perfectly designed and manufactured one, will still exhibit spherical aberration. This inherent defect of a spherical surface causes incident light rays to focus at different points and create a blur. By adjusting the surface constants and aspheric coefficients, the surface of an asphere can be designed to eliminate spherical aberration. Aspheres provide true diffraction-limited spot sizes and the lowest wavefront error. Aspherical lenses with a complex surface profile can be designed to reduce or minimize spherical aberration and also other aberrations such as astigmatism, field curvature, and distortion. In optical systems, multiple spherical elements can be replaced by a single asphere without a loss in performance. In many cases, using aspherical lenses can significantly improve the system performance and also reduce the system weight, size, and manufacture cost.
