Ball Lens
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= ...

Plano-Convex Lenses
Plano-Convex Lenses have a positive focal length and near-best-form shape for infinite and finite conjugate applications. They can be employed to converge collimated beams or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident on the curved surface of ...

Doublet Cemented Lenses
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations, Which is often designed by cementing two elements together to create smaller spot sizes. They have far superior optical performance to Singlet lenses. They offer better broadband and off-axis ...

H-K9L Cylindrical Lenses
Plano-Convex Cylindrical Lenses are ideal for applications requiring magnification in one dimension. While spherical lenses act symmetrically in two dimensions on an incident ray, cylindrical lenses act in the same manner but only in one dimension. A typical application is to use a pair of cylindrical lenses to provide anamorphic ...
