Look for Surveying Prisms that are compatible with Surveying Instruments made by Leica Geosystems, Nikon, Northwest Instrument, Topcon, CST/berger, and Sokkia.
In Surveying, prisms are an essential piece of equipment that is used to accompany tools that use electronic distance measuring (EDM). Their purpose is to reflect the beam that is used by a device with EDM, doing this informs the instrument how far the beam went which allows it to calculate the distance between the two points. This makes survey prisms essential. While some total stations have the capability to use a reflectorless option which doesn't require a prism, when a prism is used the range in which it remains accurate is largely increased.
Surveying Prisms, also known as retro-reflectors, redirect a measuring beam back to the EDM (Electronic Distance Measurement) for processing distance. When using surveying prisms, there are two main factors for good range measurement: prism diameter and beam deviation. The return beam for EDM will miss completely if the beam deviation is not accurate. This occurs mainly near the maximum range of the EDM.
Different Types of Survey Prisms?
The prism that you choose relies heavily on the type of role you need it to play. There are a variety of different types of prisms and many surveyors can find them confusing. The 360 prism works perfectly for surveyors who are working in a multi station environment. The dual sided prism would be an affordable alternative for the 360 prism. Now a mini prism would be perfect for those surveyors who don't need to take distance from an extended range.
With such a large variety of different shapes, sizes, and offsets; there are no shortage of options to choose from when it comes to selecting a prism.
