Achromatic Lens is an achromatic consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths. One frequent use is to achieve diffraction limited focusing of a laser beam. Negative Achromats are typically used when there is a need to eliminate chromatic aberration. In addition to reducing chromatic aberration at the design wavelengths, spherical aberration and coma are greatly reduced.China Star Optics can provide Positive Achromatic Lens and Negative Achromatic Lens by two piece single lens (Doublet) or three piece single lens (Triplet).
Types of Achromatic Lens:
Achromatic doublets are one of the simplest achromatic lenses, which are cemented achromats made of two different lenses.
Oplens offer achromatic doublets, cylindrical achromatic doublets, and air-spaced achromatic doublets, as well as achromatic triplets that allow for maximum aberration control. Of course, achromatic lenses can also be composed of multiple lenses, depending on their uses.
