The invention furthermore relates to an optical distance measuring device (1).

The optical distance meter further comprises an evaluation unit that detects a signal based on the detected radiation amounts, said signal depending on the distance of the optical distance meter to an object.

An optical telemeter (7) placed on the outer tip of the needle makes it possible to know the depth of the examined area.

Thus a small optical distance sensor can be produced inexpensively without requiring an expensive three-layer waveguide and an optical fiber difficult to handle.

The civilian laser range finder is light in weight, small in size, simple in operation and accurate, and its error is only one-fifth to one-hundredth of the other optical range finder.

The laser range finder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one-fifth to one-hundredth of the other optical range finder.

The optical range-finder (base 67 mm) is linked with the focussing system.

A fixed focus distance sensor element array assembly (21b) and optical distance sensing enable automatic initiation of exposure when the image is in-focus (Fig. 4).

The invention relates to a receiver lens system (7) for an optical distance measuring device (1), for detecting a light radiation reflected at an object, with a plastic lens (12) arranged in a beam path (6).
