Negative Achromats consist of two optical components, a crown and a flint glass lens, cemented together. The crown is usually a bi-concave lens. As is true to all Achromats, they are corrected for color and on-axis spherical aberration. They are used predominantly to extend focal lengths in... [See More]

A cemented cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point focusing spot, a cylindrical lens can produce a linear focusing spot. Our cylindrical achromatic doublets are... [See More]
