Mini Prisms with tilt function
RSMP280 and RSMP380

Mini prism RSMP280 with silver coated Ø 17.5 mm prism, tilting and combinable
Mini prism RSMP380 with with silver or copper coated Ø 25.4 mm prism, tilting and combinable

RSMP280 and RSMP380 can be simply glued or fixed with dowels and screws, even on difficult bases, such as glass and marble facades, historic buildings, steel beams, rails, gas and oil pipelines, etc.

The following accessories are offered for this product (see right):
Fixed point (Item RSFP-X80)
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
  • several prisms can be combined with one another due to the integrated connector system, making it possible to survey from different directions without having to turn the prism – see examples

When using robotic total stations

  • permanent settling measurements can be carried out during the building work
  • settling measurements are possible on railway tracks while under the load of rail traffic

When using mini prisms RSMP280 in the ATR mode ranges of 300 meters to 500 meters are obtained.

When using mini prisms RSMP380 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.

RSMP280 with 17.5 mm mini prism: offset: -11.0 (minus 11) [Leica +23.4], tilting axis height: 30 mm
RSMP380 with 25.4 mm mini prism: offset: -16.9 (minus 16.9) [Leica + 17.5], tilting axis height: 30 mm
