Mini Prisms

RSMP10 and RSMP12 

Our smallest prisms for special cases

When using the mini prisms RSMP10 and RSMP12 for settlement measurements, the spikes can be removed and thus be inserted or glued into the smallest cracks or holes. On façades, historical buildings, supports and lots of other objects, monitoring is possible with measuring points that are barely identifiable by the general public. At concrete or masonry objects, small holes can be drilled to countersink the prisms flush with the surface. 

With these mini prisms surveyors can measure in gaps, holes and corners easily and quickly. Fixed dimensions (see product drawings) give the surveyor the exact path from the point of measurement to the base of the housing or the tip of the spike.

In forensics, the use of prisms include the exact surveying of bullet holes.

PLEASE NOTE: For precise measurements, the prism must be exactly aligned with the surveying instrument!

The prisms can be used at an angle of up to 25 degree.  

In the event of problems with the angle or when measuring from greater distances, we recommend our tilting mini prisms: RSMP380, RSMP380M, RSMP390, RSMP390M, RSMF12 and RSMF52 

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