Binocular telescope with auxiliary lens system |
摘要 |
Auxiliary lens cylinders constituting a tele-or wide-conversion lens system can be held in and away from the front of the objective lenses of a binocular telescope, so that the main lens system of the binocular telescope can be converted to a highly magnifying tele-conversion or wide-conversion system without influencing the position of image obtained with the main lens system.
