Patent ID: 8068215

Claim:
A long-distance electro-optic laser for measuring distance between a measurement object and a reference point in a laser system, the laser meter comprising a hand-held housing ( 2 ); an electric radiation source ( 3 ) for generating a bundled light beam ( 4 ); receiving optics ( 5 ) including a photoreceiver ( 7 ) for receiving parts of the light beam ( 4 ) that is backscattered in a reception beam bundle ( 9 ) from the measurement object ( 8 ) along a reception axis (E), and a receiving lens ( 11 ), the photoreceiver ( 7 ) being arranged along the reception axis (E) in a focal point ( 6 ) of the receiving lens ( 11 ) and extends in a plane transverse to the reception axis (E); and a polarization filter ( 10 , 10 ′, 10 ″, 10 ′″) for suppressing at least those components of the reception beam bundle ( 9 ) which are polarized parallel to polarization of the light beam ( 4 ).
