An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

An imaging unit 3 is provided which includes an attachment member that is attached to a mobile terminal which includes an imaging section and a lighting section, an optical member OP (OP1, OP2) that supplies illumination light from the lighting section in an oblique direction to a part to be imaged of an imaging target imaged by the imaging section, and a shading member SL which encloses a periphery of the optical member OP. A first optical axis of the light from the optical member OP is incident into the imaging target in a direction oblique to a second optical axis of an optical system acquired by the imaging section.

An optical system, a stereoscopic imaging device, and an endoscope each provides a small size and capable of obtaining a stereoscopic image with a high resolution and a wide observation view angle. An optical system 1 includes, in order from an object side to an image plane side, a front group Gf including a first front group Gf1 arranged centering a first front central axis Cf1 and a second front group Gf2 arranged centering a second front group central axis Cf2 as a rotation symmetry axis extending parallel to the first front group central axis Cf1; and a back group Gb arranged centering a single back group central axis Cb. A central principal ray of a first light beam L1 that has passed through the first front group Gf1 and a central principal ray of a second light beam L2 that has passed through the second front group Gf2 do not cross each other from when they exit from the back group Gb to when they reach the image plane.
