Abstract
A lens system including a first substantially hemispherical lens, a second spherical lens and a third substantially hemispherical lens. The lenses are held together by a bonding material such as epoxy, which may also include a light absorbing dye. The invention also relates to a low-cost method of manufacturing the lens system out of glass, using low cost glass ball lenses to create the hemispherical lenses.
