範囲第１項記載の細隙灯顕微鏡の照明装置。[Claims for Utility Model Registration] 1. A light source device for illumination that emits a luminous flux, a slit plate having a slit arranged in the optical path of the luminous flux, and a projection that projects the luminous flux that has passed through the slit of the slit plate onto a subject. 1. An illumination device for a slit lamp microscope, comprising a lens and means for extracting a luminous flux incident on a portion of the slit plate that does not contribute to slit illumination and projecting it onto a subject. 2. Practical use characterized in that the entrance side surface of the slit plate is a reflective surface, this reflective surface is tilted with respect to the optical axis, and the reflected light from this reflective surface is projected onto the subject. An illumination device for a slit lamp microscope as claimed in claim 1.
