Custom Aspheric Lenses

An aspheric lens is used to correct for spherical aberrations, where the converging rays from a lens do not have a common focal point, which is an issue seen in traditional spherical lenses. This non-convergence of light causes a blur at the edge of an image which can be problematic in certain imaging and laser applications.

Knight Optical can provide custom aspheric lenses in Schott (or equivalent) glass types, as well as in plastic and infrared materials, such as germanium and zinc selenide. Our aspheric lenses are manufactured to your specific requirements.

Please find our typical manufacturing capabilities below, however, we are always looking to expand and work with our customers on achieving their specifications, so please do not hesitate to contact our technical sales team for further information and guidance on your enquiry:
 

 
Knight Optical can provide:

• Plastic aspheric lenses which are a cost effective solution. This can be mass produced, however the surface quality is reduced in comparison to our other lens types. An advantage of injected moulded lenses is that a flange can be added for easier assembly within a system. Knight Optical stock plastic aspheric lenses with focal lengths ranging from 3.5mm to 85mm.
• Moulded glass aspheric lenses, where surfaces are polished to meet our customer requirements.
• Knight Optical can provide, and already stock, fire polished aspheric lenses which have a large aperture, ideal for light collecting applications such as condenser lenses in LED based projects.
• Diamond turned aspheric lenses for precision grade lenses, typically used for infrared optical components.
