Lenses
Lenses have many applications ranging from the simple collection of a laser beam to precision imaging and image transfer. Lenses are classified as single lenses, cylindrical lenses and achromatic lenses. These lenses are made of BK7, fused silica and CaF2. Special focusing systems can be designed by our engineers upon request.

PROPERTIES AND APPLICATIONS

Plano-Convex Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass



Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.

Double-Convex Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass



Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.

Plano-Concave Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass



Negative lens with the form most suitable where one conjugate is more than five times the other, e.g. producing divergent light from a collimated input beam.

Double-Concave Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass

Negative lens with the form most suitable to producing divergent light or a virtual image, where the input light is converging.

Positive Meniscus Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass



These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.

Negative Meniscus Lens

BK7/ Fused Silica/ Sapphire CaF2/other optical glass



These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.

Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling.
Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request.
Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications.
Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.
