Introduction:
The Leica GMP101 offers great positional accuracy and is stored conveniently in the instrument container. The GMP101 has a built-in leveling bubble and supplied with an attachable spike (Leica snap-in mount). With this arrangement a point can be measured with very high precision.
Overview:
GMP101 Mini Prism , includes bubble, target and spike, in bag. Also suitable for GLS11 prism pole and GRT144 prism carrier with Leica snap in mount (Same height with GPH1, additive constant +17.5mm).
Centring accuracy:
Measurement errors occur if original prism holders are not used. Substitutes are not configured according to Leica Geosystems criterion and often exhibit displacement between prism, holder and mounting stub. Range The beam deviation of a prism defines the maximum range. The smaller the beam deviation (measured in angular seconds), the greater the directly reflected signal strength to the sender optic.
Lifetime:
In contrast to many conventional prisms, the reflective copper coating on the reverse side of original prisms consists of an adhesive coating, a copper coating, a protective coating and an overlying coat of lacquer. Working together, the copper coating and the lacquer increase the life of the prism significantly. An additional anti-reflex coating on the sensitive front surface provides a tough resistance to scratches.
Measurement accuracy:
Measurement errors occur frequently at close ranges when prisms without anti-reflex coating are used, as the front of a prism always directly reflects a certain percentage of a signal.
