Abstract
The invention belongs to an adjustable illumination system for an operating microscope. The illumination system is composed of a light source, a condenser assembly, a movable reflection assembly and a static reflection assembly. The inclined angle between the optical axis of illumination light reflected by the static reflection assembly and the optical axis of a large object lens is 6 degrees, the movable reflection assembly is mounted to a movable mechanical mechanism, and the movable reflection assembly can move along with the optical axis of the illumination light before reflection. The inclined angle between the reflected illumination light and the large object lens can be changed from -6 degrees to 6 degrees by moving the movable reflection assembly, so coaxial illumination can be achieved, and 0 degree illumination and coaxial illumination can be achieved at the same time.
