Abstract
The invention provides an electro-optical distance measuring instrument, which comprises a light projecting optical system for projecting a distance measuring light as emitted from a distance measuring light source on a distance measuring optical axis, and a light receiving optical system for receiving a reflected distance measuring light from an object to be measured and for guiding to a light receiving element, wherein the light projecting optical system and the light receiving optical system are disposed so that a projection optical axis and a light receiving optical axis cross each other, an optical path splitting component for reflecting the distance measuring light to a crossing position of the projection optical axis and the light receiving optical axis and for passing through the reflected distance measuring light is provided, and optical path length adjusting components for correcting an optical path length of the reflected distance measuring light are disposed on the optical path of the reflected distance measuring light.
