PMMA Polymer Aspheric Lens

Polymer Aspheric Lens or Aspheric Lens is a Lens whose surface profiles are not portions of a sphere or cylinder.

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 often cheaper than the multi-lens design.

Polymer Aspheric Lens are used for Imaging Purpose, it also can be used for Virtual Realty which is widely used now days for 3D Experience. Small molded Aspheres are often used for collimating diode lasers.
