An optical receiver lens has a three-dimensional lens surface, for receiving the laser radiation of a laser distance measuring device, said laser radiation being reflected at an object, wherein the receiver lens can be described in a three-dimensional coordinate system having three axes x, y, z arranged at right angles with respect to one another and wherein the z-axis coincides with the optical axis of the receiver lens. At least one non-spherical area section of the lens surface can be described by addition of a first area, the flexure of which along the z-axis is a first function (f) of x and y, in particular of (I) and a second area, the flexure of which along the z-axis is a second function (f) of x and not of y. A distance measuring device is also described.
