Features: Simplified structure,reduced weight and size,surface profile neither a sphere or a circular.

Applications: Photographic camera lens and viewfinder, television camera tube, zoom camera lens satellite infrared telescope, video camera lens.

A Paraboloid aspheric lens or asphere is a lens whose surfaces have a profile that is neither a portion of a sphere nor of a circular cylinder, but like paraboloid profile. Because asphperical lenses have different radius of curvature from surface center to edge, so aspherical lenses can eliminate spherical aberrations as well as the error which other spherical lenses can not eliminate, promote spotlight accuracy rate. At the same time, an aspherical lens has a simple construction, an aspherical lens can replace multiple lenses system, thereby reduce weight, size, and cost.
