DEFLECTION ADAPTER FOR LASER-LEVEL SURVEYING APPARATUS

摘要

PURPOSE: To set the emitting direction (bearing) of a laser beam, whose direction is inclined by 90 degrees with respect to an incident angle, accurately and to confirm the direction. ;CONSTITUTION: A deflection adapter is attached to a laser-level surveying apparatus 1, which contains a laser light source in an apparatus base stage 2 and emits a laser beam A at least in the horizontal direction, and deflects the direction of the beam A. In this deflection adapter, a prism, which deflects the beam A by 90 degrees with respect to the incident angle, is contained. A deflection- adapter main body 12, which is mounted in front of a laser beam emitting hole 3 of the apparatus base stage 2 so that the main body is turned, attached and removed freely, is provided. A bearing level 13, which sets the bearing reference of the laser beam B after the deflection, is fixed and mounted on the adapter main body 12.;COPYRIGHT: (C)1996,JPO
