Optical Mini Glass Bk7 Dome Lens K9 od3.98 inch Hemisphere Guide Top Camera Coating Dome Lens For Video Camera
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 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.
