Achromatic doublet lenses

What are you looking for in Stock?

A single lens used to form an image will always show some chromatic aberration, that is variation of focal length with wavelength. Achromatic doublet lenses correct for this as they are constructed from two different glass types and designed to remove first order chromatic aberration. Generally spherical aberration is reduced at the same time. Achromatic doublets are probably the most economical way of achieving quality white light illumination and imaging.

Knight optical stock a range of doublet lenses in various forms and quality from small 3mm dia up to 110mm dia to meet a range of demanding applications. These stock lenses can be edged down at short notice to meet your specific custom requirement.

Quality achromatic doublet lenses: A range of quality achromatic doublet lenses are available constructed from two different glass types and designed to remove first order chromatic aberration. Generally spherical aberration is reduced at the same time.


 Achromatic doublets are widely used to form images, for example telescope objectives, and also to focus laser beams. These quality achromats have been designed and optimised for performance and are available as positive and negative focal length types. We stock a full range of doublet lenses from small 3mm dia up to 110mm dia to meet a range of demanding applications. Typical applications where achromatic doublet lenses are used are imaging, analysers, fibre-optic lighting, laser range finders endoscopes and borescopes. We can offer custom achromatic doublet lenses to meet your requirements or alternatively edge stock lenses for a quick turnaround, please enquire.

Commercial doublet lenses: Our commercial grade achromatic doublets are largely similar to the quality doublet lenses but not made to such stringent tolerances. They are used for more general-purpose applications not requiring high quality, such as experimental and educational demonstrations.
 

Cylindrical doublet lenses: Knight optical cylindrical achromatic doublet lenses are used to focus light in one direction but at the same time reducing chromatic aberration which ordinary singlet type cylindrical lenses don’t achieve. Typical applications for cylindrical achromatic doublet lenses are changing the profile of laser beams, for example to correct for astigmatism and ellipticity in diode lasers or to generate lines form single mode lasers and focusing a beam onto linear detector arrays.

Achromatic doublet lens sets: We stock a range of doublet lens sets for ease of use in a laboratory and design environments. These doublet lens sets are more economical to buy compared to buying as individual lenses.
