These prisms are manufactured from high-quality optical glass which is worked to strict specifications. All reflective surfaces are provided with a resistant coating so that the reflectivity is not adversely affected by dirt or condensation.
Conveniently storable in the instrument container, Mini Prisms offer a high positional accuracy due to their small size. The GMP111 has a built-in levelling bubble and is supplied with an attachable spike (1/4" thread). With this arrangement a point can be measured with very high precision.
