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.
