Product Description

GPR1 Prism Holder Surveying Reflector Prism Accessory for Survey EDM Instruments


GPR1 Overview:


The GPH Prism Holder for Leica GPR1 Circular Prism is a special accessory used to hold circular-shaped prisms for a more convenient use.


Circular prisms, such as the Leica GPR1, easily fit into this holder and does not easily fall off. With this holder, reflectors can be snapped on to poles like the Leica GLS11.


The GPH holder is made of fiber-reinforced polymer and can fit either one or three prisms. It also allows a 360-degree horizontal rotation.


GPR1 Features:

  • Firmly holds circular prisms
  • Easily snaps on to prism poles
  • Made of Fiber-reinforced polymer
  • 360° horizontal rotation
  • For Leica GPR1 Circular Prism
  • Compatible with Leica GLS11 prism pole

Optical Surveying Reflector 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:

  1. Rail Monitoring
  2. Settlement Monitoring
  3. Displacement Monitoring
  4. Deformation Monitoring
  5. Convergence Monitoring


Optical Surveying Reflector 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 of 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

Leosurvey provides a wide range of total station survey prisms for every application. Our premium quality prisms have been rigorously tested and are trusted by our customers to provide reliable and accurate measurements on large construction projects. The optical prisms we provide can be used with any brand of total station including Topcon, Sokkia, Leica Geosystems, Trimble Geospatial, Nikon and GeoMax.
