The purpose of the present invention is to provide a compact optical system for stereoscopic imaging capable of obtaining a high-resolution stereoscopic image with a wide angle of view, a stereoscopic imaging device, and an endoscope. The optical system (1) for stereoscopic imaging is provided with, in order from the object side, a front group (Gf) comprising first and second front groups (Gf1, Gf2) having parallel but separate front group central axes (Cf1, Cf2) as their respective centers, and a back group (Gb) with a single back group central axis (Cb) as its center. The back group (Gb) comprises: a first back group (Gb1) on the object side; a second back group (Gb2) on the image side; first and second openings (S1, S2) arranged between the first back group (Gb1) and the second back group (Gb2) and arranged so as to be symmetrical to each other with respect to a plane that is orthogonal to a plane including the front group central axes (Cf1, Cf2) and that includes the back group central axis (Cb), said first and second openings (S1, S2) having first and second opening centers (CS1, CS2) which deviate away from the back group central axis (Cb); and first and second deflection groups (Gv1, Gv2). |
