17.5mm Mini Prism w/180° Rotation Series

With the 3345 Series 17.5mm Mini Prism w/180° Rotation, the measuring points can always be exactly aligned on the measuring instrument and turned in a radius of 180°. This enables the use of the same survey point from different directions. Bridges, facades and many more structures can be observed quicker and more accurately. Several prisms can be combined with one another with the integrated plug-in system, enabling measurement from different directions, without the need to turn the prism. After completion of the measurements the prisms can be quickly and easily taken off, and, if necessary, plugged-in again. An unplugging of the prisms in the alignment enables the measurement from almost all directions. Provided holes permit attachment with dowels and screws.

In the ATR mode ranges of 500 m to 700 m can be achieved. The ranges are dependent on the type of instrument used and are affected by the weather and environmental conditions.
