Abstract
A binocular is provided with a pair of telescopic optical systems. Each of the pair of telescopic optical systems has an objective lens, an erecting system, a compensation lens and an observing optical system. The erecting system of each of the telescopic optical systems is divided into two sub prisms, a vertically extending optical axis is defined therebetween. The compensation lens is located between the first and second sub prisms such that it is movable in a horizontal plane by a driving mechanism. As the compensation lens moves, an optical path of light passed therethrough changes. Accordingly, by driving the compensation lens in accordance with the hand-vibration, trembling of the image can be compensated.
