LASER MINILEVEL Russian patent published in 2004 - IPC

FIELD: geodetic instrumentation engineering. SUBSTANCE: laser minilevel comprises frame in the form of duralumin U-shaped cramp, cylindrical level gauge, optical sight, laser pointer and mechanism for orientation of body in space. Axes of level of optical sight and laser pointer are parallel. Laser pointer has special slit nose piece enabling collimated luminous flux to be distributed so that it transforms into horizontal line. Mechanism for orientation of body in space includes collet clamp, location bushing, elevation screw, fixing screw, rotation axle of instrument, mechanism makes it possible to orient minilevel in horizontal, inclined and vertical planes. EFFECT: compactness of minilevel making it possible to execute geodetic survey and showing sufficient precision in conducting earth-moving and assembly operations under conditions of construction site. 2 cl, 1 dwg
