Aspherical Lenses

Aspherical lenses are designed to have a much shorter focal length than is possible with regular spherical lenses. They are also corrected for spherical and coma aberrations. Ideally suited for low f-number and high throughput application, condenser quality aspheres are primarily used in high efficiency illumination systems.
