::: Plano Convex Lenses (PCX) ::: 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.

::: Symetric Convex Lenses (SCX) ::: SCX lenses have two symmetrical convex surfaces and positive focal length. They are used for condensing, magnifying and to form real or virtual images.

::: Plano Concave Lenses (PCV) ::: PCV lenses have one flat side and one inward curving surface and negative focal length. They diverge incident light, and generally form virtual images, which could be seen through the lens. PCV lenses offer a very nearly minimum spherical aberration at negative-infinite or near-infinite conjugate ratios with the concave surface facing the longer object or image distance. These lenses are usually used as light beam expanders or to increase focal length in existing system.

::: Symetric Concave Lenses (SCX) ::: SCV lenses with two symmetric inward curving faces have negative focal length, diverges incident light and generally forms a virtual image. Like the PCV lenses, they are often used to expand light beam or to increase the focal length. These types of lenses are normally used in devices such as laser beam expanders, projection optics, etc. in combination with other lenses.
