PCX Lenses have one flat and one outward curving faces and positive focal length. These lenses can be used for condensing, magnifying and to form real or virtual image. When used for focusing or collimating, the curved surface always faced to the collimated light, when the lenses is used for imaging, the curved surface must be closed to the object or image for which the conjugate distance is longer. This will form an image with diminished aberrations. The lenses are often used in telescope, collimators, magnifiers and condensers.
