Bi-concave (BCV) Lens / Double Concave (DCV) Lens, custom
The Bi-Concave / Double Concave Lens has a focal length, diverges collimated incident light, and forms only virtual images that are seen through the lens. It's often used to expand light beams or to increase focal length in existing systems. The BCV / DCV lens is normally used in combination with other lenses. In a single lens application you should consider using them in preference to a single plano-concave lens if the magnification lies in the region. They are widely used in telescope, collimators, optical transceivers, magnifiers, radiometers and condensers.
Creator Optics can custom produce various AR coated and uncoated bi-concave / double concave lenses. These BCV / DCV lenses are usually made of following materials:
In addition to the traditional form factor, the company can also provide double concave lens with special shapes, such as a double concave lens with a cut shape ( special cutting lenses ), rectangular, step edge and so on.
Surface Quality: 80/50, 60/40, 40/20, 20/10, 10/5.
