Abstract: A vari-focal polar alignment scope includes an objective optical system, a relay optical system, and an eyepiece optical system, in that order from the object side. The relay optical system includes an erecting vari-focal viewing optical system, including a positive condenser lens element, and positive second and third relay lens groups which relatively move in the optical axis direction so as to vary the magnification of the polar alignment scope, wherein the following conditions (1), (2) and (3) are satisfied:6.0

Abstract: An image-erecting viewing optical system includes a first prism having an incident surface and at least two reflection surfaces, a front lens group of an objective optical system, a second prism having an incident surface and at least two reflection surfaces, a-rear lens group of the objective optical system, a field stop, and an eyepiece optical system, in this order from the object. One reflection surface of the first or second prism includes a roof-mirror surface. The following conditions are satisfied: sin(nullnullnullnull)>1/n nullnull(1) 6null
