In the slit illumination device, when the focal length of the projection lens is f1, and the object-image distance between the slit aperture and the slit image is 1, the projection lens is d−(−−m)′fn] where (↓-2) By moving to the two positions determined by the tenth core 1 t' 2 , m times and 1 times 2 can be obtained without changing the object-image distance 1.
An ophthalmological slit illumination device characterized by being capable of obtaining two slit projection magnifications.
