CRYSTECH, Inc. Datasheets for Meniscus Lenses

Meniscus lenses are optical lenses that produce a smaller focal point and fewer aberrations than a standard plano-convex lens. They have one convex and one concave surface with each surface having its own radius or curvature.

Product Name Notes
Optical Lenses -- Cylindical Cylindical Lens: Used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images.
Optical Lenses -- Double-concave Double-concave Lens: Negative lens with the form most suited to producing diverging light or a virtual image, where the input light is converging.
Optical Lenses -- Double-convex Double-convex Lens: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.
Optical Lenses Lenses have many applications ranging from the simple collection of the scanning of laser beams to precise imaging and image transfer. CRYSTECH provide these lenses for different application. Plano-convex Positive...
Optical Lenses -- Meniscus(Negative) Meniscus(Negative) Lens: The best lens form where one conjugates is relatively far from the lens or where both conjugates are the same size of the lens.
Optical Lenses -- Meniscus(Positive) Meniscus(Positive) Lens: These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.
Optical Lenses -- Plano-concave Plano-concave Lens: Negative lens with the form most suitable where one conjugates is more than five times the other, e.g. producing divergent light from a collimated input beam.
Optical Lenses -- Plano-convex Plano-convex Lens:Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor application or for use with near collimated light.
