Trimble VX&S Series 360° Prism

Prisms have a wide range of surveying applications as they can be used in conjunction with Total Stations. There are also different types of surveying prisms, meaning you can find exactly what you need for your project.

In the SEP Geospatial shop you’ll also find Prism Adapters that enables greater flexibility of use with these products by attaching to surfaces. This is most effective when combined with Prism Poles to allow surveyors to access challenging areas.

We’ve got a massive range of prism types and accessories to meet project requirements. With Mini Prisms you can access hard-to-reach areas without adding time onto the project. Traverse Prisms and Kits are ideal for increasing precision. Then if you need devices to complement GPS equipment, we have large and small Monitoring Prisms for seamless integration.

About Our Prisms

Looking for a versatile prism to enhance your surveying accuracy?: Prisms are highly flexible pieces of surveying equipment that can be utilised in a wide variety of applications. This includes construction projects, land surveying, civil engineering tasks, and much more.
Stocking prisms of premium brands.: At SEP Geospatial, we pride ourselves on the fact that we are trusted suppliers of the most effective and highly performing surveying equipment on the market. Our range of prisms and associated accessories includes products from the likes of Trimble and Leica.
What is the purpose of a Survey Prism?: The primary purpose of a surveying prism is to reduce the scatter of EDM signals. This allows equipment to achieve more accurate and longer range measurements. Prisms can also help surveyors map certain areas without the need for physical access, which improves both safety and efficiency.
Which Prism coating is best?: Over the years, prism coatings have been made from a range of materials including copper, silver, and dielectric materials. Nowadays, silver is a common choice in the construction of surveying prisms due to its high reflectivity.
How do you use a Survey Prism?: When using a survey prism in conjunction with a total station, first place the prism pole vertically in an unknown site point. Aim the prism so it can see the total station, then adjust the total station so it can sight the prism. After the completion of any other pre-measurement checks, you’ll be ready to start capturing data.
What is a monitoring Prism used for?: Also known as ‘optical survey prisms’, monitoring prisms allow for the calculation of precise distances, as well as resolve horizontal and vertical angles to the prism. These glass reflectors can be used with total stations and automated motorised total stations (AMTS).
