Objective Lenses of f/1 Aperture and Greater
The factors involved in the design of large-aperture objectives are discussed and some of the general approaches to the reduction of the various aberrations are presented. Diagrams, classification, and source references of most objectives of f/1 aperture or greater which have been published are included. Both refracting and reflecting systems are considered, including objectives having spherical and aspherical surfaces and those employing the immersion principle. Applications, testing, and performance of extreme-aperture objectives are discussed. An extensive bibliography is appended.
