- W3096128270 abstract "To find the focal length, f, of a positive lens, the apparatus is arranged as shown in Fig. 83. The laser, the object-image screen, the lens, and a front-surface plane mirror are mounted on an optical bench. The object-image screen is a white, 7.5 cm x 12.5 cm (3” x 5”) filing card. A small hole is punched in the center of the card and a piece of tracing paper is fastened with adhesive tape to cover the hole. The raw laser beam is aimed to impinge on the center of the tracing paper. The bright red spot on the translucent paper is the “object”. The lens to be measured and the plane mirror are set up close together. The light leaving the lens is interrupted by the mirror whose reflective surface is approximately square to the laser beam axis. If the tracing paper is situated exactly in the principal focal plane of the lens and the mirror is exactly at right angles to the laser beam axis than the light rays are reflected back exactly upon their original paths. If, however, the mirror is inclined at a small angle, T, to the axis, the incident light rays are reflected back at an angle, 2T, and the image of the bright red spot will be formed on the white card screen instead of the tracing paper. By sliding the lens-mirror combination back and forth along the axis a sharp image of the bright spot is obtained on the white card. The distance between the card (object-image screen) and the lens is the focal length." @default.
