WebBonus: A brief story of H. D. Taylor, inventor of the Cooke Triplet. Taylor had developed other optical systems besides the Cooke Triplet, such as telescope objectives, various eyepieces, and the first lens coatings. In 1906, Taylor’s major written work, A System of Applied Optics, was published, followed later by a German translation.

WebSummary. Optical systems comprise lenses and mirrors made with precise surfaces. Optical surfaces can be divided into spherical and nonspherical surfaces; the latter are called aspheric surfaces. For a given image quality, the choice of optical surfaces has a major impact on the packaging and cost of a lens system.
