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.

  1. With 360° prism
  2. Prism is lightweight
  3. It is sturdy and durable and a good helper for measuring tools.
  4. Pole diameter 12mm
  5. 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
