Abstract: An optical instrument including means for selecting one of several magnifications of an image being viewed, the selective magnification means being positioned in a collimated light path between an objective lens and a viewing lens and without change of conjugate distances therebetween; also an aperture stop located at one conjugate plane of a relay lens, the other conjugate plane being the nodal plane of the objective lens, which serves as a light-attenuating means without interference with the viewing optical system or without affecting the field being measured.
