Abstract
A laser distance measuring device comprising a transmitter channel (1), a receiver channel (2) and a dimensionally stable multilayer base printed circuit board (3), with the transmitter channel (1) and the receiver channel (2) being mounted and symmetrically disposed one on each side of the base printed circuit board (3), with the base printed circuit board (3) 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.
Claims10
A laser distance measuring device comprising:
- a transmitter channel and a receiver channel, wherein said transmitter channel comprises a laser transmitter and an optical transmission system which together define a transmission axis, and said receiver channel comprises a receiver and an optical reception system which together define a reception axis, wherein said reception axis is aligned parallel to the transmission axis, and
- a printed circuit board which is opaque to the radiation of the laser transmitter, and upon which the laser transmitter and the receiver are mounted, wherein the laser transmitter and the optical transmission system are disposed on one surface of the printed circuit board, and the receiver and the optical reception system are disposed upon the opposite side,
- wherein the printed circuit board is a dimensionally stable multilayer base printed circuit board.
