Ball Lens

BoJen Optics, Inc.

Add to watch list

Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. The focal length can be calculated as the following equation: f= ...

FIFO-plano-concave lens

FIFO OPTICS CO., LTD

Add to watch list

Plano-Concave lens has a negative focal length, diverges collimated incident light, and forms only virtual images which are seen through the lens. It is often used to expand light beams or increase focal lengths in existing systems.

FIFO-plano convex lens

FIFO OPTICS CO., LTD

Add to watch list

Plano-convex lenses are used to collimate diverging light or to focus collimated light. We use them as secondary focusing lenses to refocus the collimated light sources.Plano-convex lenses have low spherical aberration. Use them with the plano side facing the point source or the focus and the curve side towards the collimated beam.

BK7 BiConcave lens

Sinocera Photonics, Inc

Add to watch list

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or ...
