Basics of Prisms & Prism Constants
In surveying, electronic distance measuring (EDM) instruments alone are not enough for the task of distance measurement. There needs to be a surveying prism as well to catch the beams transmitted by the EDM device, correct these beams, and return them to the device. However, it isn’t as simple as that. When using prisms, surveyors must understand all there is to know about these corner cubes, and one of the most essential things to know is the prism constant.
The prism constant can be a confusing subject in surveying, especially for those who are still new to using prisms. Fortunately, this video clearly illustrates what prism constants are, and it explains everything in a way that’s easy to understand.
Surveying Prisms
Measuring long distances outdoors is a must in surveying projects. This task requires the use of electronic distance measuring (EDM) instruments, such as total stations, which usually needs targets to measure vertical and horizontal angles, coordinates, and distances of slopes. Because these instruments produce waves when ranging, the targets that perfectly complement them are retroreflectors or prisms. Prisms can reflect light back toward the instrument in a straight direction without scattering it. They can therefore help surveyors establish control points with high accuracy at a comfortable height. When choosing which prism to use for surveying, Engineer Warehouse has carefully selected the best prisms that will surely suit your needs. Since the light beams generated by EDM instruments take a longer time to exit the prism, the accuracy of the distance measured is adversely affected. This is why most of these prisms have 0/-30mm offset, which means that they correct the distance measured by altering the transmitted light coming from the instrument. These prisms are guaranteed to have high-quality glass, assemblies, and refractive index for accurate measurements and optimal performance. Constructed with durable materials, these prisms will surely last through years of surveying.
