Product Description

MPR122 360° Reflector Pro Prism With 5/8" Thread Leica High Accuracy 360 Degree Prism

 

Model: MPR122

 

Specifications:

Prism Type 360 Degree
Prism Constant 28.1mm
Centering Accuracy ±2.0mm
 Adaptor Thread 5/8"

 

Features:

The MPR122 is a high accuracy (±2mm) 360° prism which has now been utilised in the iCON product line.

Used in conjunction with the CRP1 pole. For monitoring applications the larger size of the MPR122 over the GRZ101 and L-bar designs means that ATR will locate at greater ranges.

 

360 Degree Prism

Instead of a single tripleprism glass assembly, the 360° prism consists of six tightly assembled triple prism glass bodies.

Each body is comparable to a single round prism but with smaller dimensions and with only slightly ground corners.

This type of prism provides a continuous and permanent reflection of the EDM signal.

 

Range
The beam deviation of a prism defines the its maximum range, according to the principle "entering beam should equal the exiting beam". The smaller the beam deviation (measured in angle seconds), the greater the directly reflected signal strength to the sender optic. The returned signal quality defines the maximum range of a measurement.

Lifetime
In contrast to many conventional prisms, the reflective copper coating on the reverse side of Original prisms consists of a support coating, a vacuum-metallised copper coating, a protective coating and an overlying coat of lacquer. The special adhesive lacquer protects the underlying layers from corrosion and detachment. 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 of the prism provides a tough resistance to scratches. The production process of these coatings is so complex that only a very few manufacturers worldwide meet the requirements of Leica original prisms.

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. Errors occur in the use of prisms without copper coating on the back side when moisture droplets accumulate or the prism becomes foggy. Leica Geosystems therefore uses either the stated reflective coating or a patented system for the prevention of fogging and condensation.


 

Optical Survey Prism Applications

Surveying reflector prisms are used by surveyors and engineers to measure the change in position of a target that is assumed to be moving. Survey prisms are used for a wide range of monitoring applications including:

· Rail Monitoring

· Settlement Monitoring

· Displacement Monitoring

· Deformation Monitoring

· Convergence Monitoring
