Abstract
A mounting base which includes an object side portion, an eyepiece side portion, and a connecting portion. The connecting portion connects the side portions, and the side portions are parallel. A pair of first mounting holes are formed in the object side portion and a pair of second mounting holes are formed in the eyepiece side portion. An axis line, perpendicular to the object side portion, which goes through a geometric center of gravity of one of the first mounting holes is coaxial with an axis line, perpendicular to the eyepiece side portion, which goes through a geometric center of gravity of one of the second mounting holes. Lens barrels of the objective lenses are fixed to the first mounting holes. Eyepiece units, in which the eyepieces are held, are rotatably engaged with the second mounting holes.
