Anchor Optics® (Barrington, N.J.) announces the availability of Commercial Grade Large PCX Condenser Lenses. Our large plano-convex (PCX) condenser lenses, used in illumination applications, are ideal for collecting and directing light from large angular area sources. A larger lens equals a greater area with which to collect light. Available in sizes from 100 mm to 200 mm in diameter, these lenses can be used in large-format projectors, spotlights and enlargers. By using two condenser lenses of the same focal length, you can produce a system with half the focal length of a single lens, which provides a lower f/#, increasing the light gathering capacity of the system. Anchor Optics®' Commercial Grade Large PCX Condenser Lenses are made of polished BK7 glass, which provide increased surface quality over standard cast molded condenser lenses. www.anchoroptics.com
