Introduction:
This mini prism set is suitable for short range ATR applications.
Due to its small size, the GRZ101 provides the greatest pointing
accuracy of 1.5mm.
The reflector can be mounted on all poles with stub fitting.
ART range of 350m.
Features:
- With 360° prism
- Prism is lightweight
- It is sturdy and durable and a good helper for measuring tools.
- Pole diameter 12mm
- Suitable for all short range ATR applications.
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
Prism Range
Surveying Prisms, also known as retro-reflectors, redirect a
measuring beam back to the EDM (Electronic Distance Measurement)
for processing distance. There are two main factors for good range
measurement: prism diameter and beam deviation. If the beam
deviation is not accurate then the returned beam will miss the EDM
completely. This occurs mainly near the maximum range of the EDM.
Prism Holder Accuracy
Prism accuracy is determined by the physical location of the prism
in its canister and then to the prism holder.
Optical Survey Prism Installation
Monitoring prisms should be installed using the following
guidelines:
- Attached to a rigid structure that is sufficiently stiff as to not
move through a single monitoring cycle
- Located to minimize the effects of temperature and radiant heat on
a target
- Installed with clear sight lines back to the total station
- Avoid sight lines that require shooting through a fence or another
mesh
- Avoid sight lines shooting just past corners which can cause
refraction
- Avoid sight lines that include a source of heat that can cause a
heat shimmer
Types optical survey prisms
- Mini prisms are cheap and reliable, and are a good multi purpose
prism for short to mid range measurements.
- 360 prisms are simple to use for sharing prisms in a multi station
network and all angles have a shared center.
- Dual prisms are reliable shared prisms with shared centers. They
are less expensive than 360 prisms, but have to be aimed at each
total station in a network.
- Full size reference survey prisms are ideal for high range
precision monitoring and can be used to calibrate a monitoring
network
