Abstract
An optical imaging system incorporates a beam splitter, which is moveable to a beam-splitting position where the beam splitter intercepts the light on an input optical path and a non-beam-splitting position where the beam splitter is located outside of the input optical path. The beam splitter includes a body penetrated by an aperture and a reflective surface surrounding the aperture. When the beam splitter is located in the beam-splitting position, a portion of the light in the optical path is transmitted through the aperture and a portion of the light in the optical path is reflected from the reflective surface.
