A laser distance measuring device comprising a transmitter channel (), a receiver channel () and a dimensionally stable multilayer base printed circuit board (), with the transmitter channel () and the receiver channel () being mounted and symmetrically disposed one on each side of the base printed circuit board (), with the base printed circuit board () serving as a mechanical foundation, as an optical and electrical shield, as a carrier of electrical and optical connections and, optionally, as a heat conductor.

Compact laser rangefinder

An electro-optical distance measuring system ( ) for large measurement ranges having a para-axial arrangement of a beam source ( ) with a transmitting optics ( ) and a beam receiver, configured as at least one small-area photodiode ( ), with an associated receiving optics ( ), which contains the processes for signal extension for the lower distance measurement range for distances (X). The beam source ( ), the transmitting optics ( ), the small-area photodiode ( ) and the receiving optics ( ) are each oriented with their optical axes (A , A ) parallel to the measurement light beam ( ). The measurement light beam ( ) is directed from the transmitting optics ( ) to the measurement object and continues to the receiving optics. The beam source ( ) and the small-area photodiode ( ) are connected rigidly with each other by at least one rigidly connected circuit board ( ), such that at least the small-area photodiode ( ) can electrically conduct and temporarily adjust in a position ( ) at least using its electrical contacts ( ). The small-area photodiode ( ) is fixed directly in the adjusted position ( ) on the circuit board ( ).
