Abstract
PURPOSE: To produce a deformed gauss type lens, which is excellent in quality and low at production cost, by making an aperture ratio of 2.0, a picture angle of 45 degrees and the back focal length larger than 0.73, by reducing the thicknesses of respective lens components, by suitably selecting the angular distribution and the spacings of the lens sides, and by using inexpensive glass for a convex lens system.
