Laser Aspheric Lens
The aspheric lens uses a single element design, which helps reduce the number of lenses in the optical assembly. Unlike spherical lenses, aspheric lenses have a more complex surface, and the curvature of the surface gradually changes from the center of the lens to the edge of the lens. The most significant advantage is that it can correct the spherical aberration caused by the Spherical Lens in the collimation and focusing system. One of the applications of aspheric lenses includes focusing the output from a laser diode, which not only reduces the overall cost, but also outperforms components designed using traditional spherical optical lenses.
The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. Small molded aspheres are often used for collimating diode lasers.
