Abstract

A simple lathe for making hyperboloid lenses has been developed. A cutting tool revolves around the vertical tool spindle, and its edge forms a hyperboloid of one sheet of revolution. A plastic rod is chucked on the main spindle and set at right angles to the hyperboloid of one sheet of revolution formed by the edge of the cutting tool. Plastic rods are easily cut into hyperboloid lenses within 10 min. This simple lathe is very useful for preparing experimental optical systems with small aberration in the laboratory.
