Abstract

A scope includes an objective lens system having refractive power, a relay lens system having refractive power, and an eyepiece system having refractive power. The relay lens system includes a first, a second, and a third lens groups. The second lens group includes a II-2-1 lens and a II-2-2 lens, and both of which are cemented. The third lens group includes a II-3-1 lens having a convex surface facing an object side and a II-3-2 lens having a convex surface facing an image side, and both of which are cemented. The second lens group and the third lens group can move along an optical axis to change a magnification of the relay lens system and thereby change a magnification of the scope. The objective lens system, the relay lens system, and the eyepiece system are arranged in order from the object side to the image side along the optical axis.
