Meniscus Lenses

Please visit our website for more information on this topic.

Used in applications to reduce beam distortion

Other dimensions are available in small and mass production quantities

Various AR coatings are available for all these lenses. Please refer to the

Positive and negative focal length lenses have different radii on both sides. Meniscus lenses are used in applications where distortion of the beam has to be reduced. They are used on focusing beams in telescopes, collimators or condenser systems, optical transceivers or other devices. Standa provides lens with anti-reflection coating (please refer to the Coatings Section).
