- 摘要：
PROBLEM TO BE SOLVED: To provide a scanning laser ophthalmoscope which suppresses a noise caused by a rotating polygon mirror to acquire an eye-fundus image with less noise.
SOLUTION: The scanning laser ophthalmoscope, including an irradiation optical system which irradiates an eye fundus to be examined with laser beams emitted from a laser light source and has a scanning means comprising the polygon mirror and a Galvano-mirror for scanning the laser beams emitted from the laser light source on the eye fundus in a two-dimensional manner and a light receiving optical system for receiving the laser beams emitted to the eye fundus to be examined by a light receiving element to capture the eye fundus image of the eye to be examined, is equipped with a housing case which houses the polygon mirror in the inside and has an opening part for making the laser beams enter and exit with respect to the polygon mirror and a transparent member which blocks the opening part, transmits the laser beams, and is formed to make the surface of the transparent member and an extending surface of the reverse side intersect at a prescribed angle.
