The RSMP280 is a twistable, extensible 17.5 mm mini-prism made with a rugged plastic housing system.

When using the mini-prism RSMP280, the prism can always be aligned precisely with the measuring instrument. The 17.5 mm prism can be turned in a radius of 180º so the same survey point can be measured from different directions. Bridges, rail lines, buildings and other structures can be measured more quickly and precisely. With the integrated plug-in system, several prisms can be combined as needed. This permits measuring in difficult locations from different directions without having to turn the prism. Mounting adhesive enables quick and simple installation even on difficult surfaces while provided holes enable attachment with dowels or screws.

Reflectorless measurement ranges of 400 m and more are possible when using the RSMP280 mini-prism and when sighting known measuring points with robotic total stations, it is possible to achieve ranges of up to 1000 m.
