RSMP290 bis RSMP390
Mini Prisms RSMP290 and RSMP290M*
Mini Prisms RSMP390 and RSMP390M* (*magnetic)

Mini Prism RSMP290(M*) with silver coated, Ø 17.5 mm prism, can be rotated and tilted
Mini Prism RSMP390(M*) with silver or copper coated, Ø 25.4 mm prism, can be rotated and tilted

RSMP290 and RSMP390 can be quickly and easily stuck even to difficult surfaces, e.g. glass and marble façades, historic buildings, gas and oil pipelines, etc. or attached using plugs and screws. A magnetic version of the base plates is also available for easy installation on steel structures.

The following accessories are offered for this product (see right):
Fixed point (Item RSFP-X90)
Protection cap with or without magnetism (RSPC10, RSPC10M & RSPC20, RSPC20M)

When using tachometers and robotic total stations

  • the prism can always be aligned accurately with the measuring instrument
  • the prism can be turned in a radius of 180°, making it possible to use the same survey point from different directions
  • bridges, façades and many other structures can be monitored even more quickly and precisely
  • When robotic total stations are used permanent settlement measurements can be carried out during construction

When using mini prism RSMP290 in the ATR mode ranges of
300 meters  to 500 meters are obtained.

When using mini prism RSMP390 in the ATR mode ranges of
500 meters to 700 meters are obtained.

The ranges are dependent on the device and can be adversely affected by weather and environmental conditions.

When sighting measuring points that are already known, with robotic total stations it is possible to achieve
ranges of up to 1000 m. Depending on the focus, ranges of approx. 200 m are achieved for measurements in manual mode.

RSMP290 with 17.5 mm mini prism: offset: -11.0 (minus 11) [Leica + 23.4], tilting axis height: 45 mm
RSMP390 with 25.4 mm mini prism: offset: -16.9 (minus 16.9) [Leica +17.5], tilting axis height: 45 mm
