Abstract
A lens module for use in an opto-electronic range finder double ray deflection for the projection of two images of an object onto two linear image sensors disposed in a single image plane has a prismatic body having a trapezoidal base with a V-shaped notch in a central area of the longer of the parallel trapezoid sides of the base. The surfaces of the notch are substantially parallel to the nearest non-parallel trapezoid side. A projection from the shorter parallel trapezoid side has a pair of light exit ports leading to the respective image sensors and a pair of light inlet ports are disposed at opposite ends of the longer parallel trapezoid side.
