Abstract
This paper describes the design requirements of an optical system having two magnifications, one with a fixed lens system and another being obtained through the introduction of an auxiliary lens system into the optical axis of the former system. The auxiliary lens system can be swivelled-in or swivelled-out of the fixed lens optical path depending on the requirement. The mechanical design aspects of such a system have been discussed and tests carried out on it are reported. The tests have indicated that with this design the optical axes of the two systems are aligned within the permitted tolerances.
