Rothbucher Prisms Offer Easier Installation and Alignment from Any Position

Thanks to a new RS line of mini prisms from Rothbucher Systems, surveyors now have more measurement flexibility than ever before.

Mini prism with 360 degree rotationWith both 180º and full 360º swiveling capabilities, these innovative mini prisms make it possible to use the same survey point from any number of locations on-site while maintaining precise accuracy.

Using its integrated connector system, several mini prisms can be combined to make measurements in different directions while the prism remains in place––the perfect option for three-dimensional monitoring.

Watch our video below to see these new products in action and read on for more information about how they can help you work smarter on-site.

Rotational flexibility and various sizing options

With 180º and 360º rotation, surveyors now have the freedom to position themselves in virtually any location relative to the prism without losing the survey point. 

Available in a 12.7mm and larger 17.5mm size, these prisms can be used in a wide variety of applications while keeping a generally low-profile.

Innovative installation capabilities

Along with greater measurement versatility, Rochbucher Systems has also made installation fast and easy with a brand new way to recover survey points and return to them even after a prism is removed.

Remove and re-attach prisms with the RSFP-X90 Fixed Point

By attaching a simple stainless steel locking mechanism called a Fixed Point, prisms can be quickly snapped into place at a precise survey point and removed for later use––leaving only the small, low-visibility Fixed Point behind. 

RSFP-X90 Fixed Point 

This simple, yet powerful ability allows surveyors to save time that would otherwise be spent re-establishing new survey points while keeping prisms from being lost or damaged when not in use.

Fixed Points can be installed even on non-metallic surfaces like wood, stone and concrete for reliable recovery.

Magnetic Attachment

When working with ferrous surfaces, these prisms can be attached magnetically with extreme stability––a quick and easy way to establish points and make precise measurements without the need for drilling, gluing or other installation tools.

Traditional Installation

For projects requiring standard installation, all RS mini prisms allow for more permanent positioning using bolts, screws or adhesives.

Added protection from the elements

In areas prone to dirt and dust, the magnetic RSPC10M Protection Cap can be attached over the prism to shield against debris. 

For placement in hard-to-reach areas, the RSPC Metal Cube attaches to any prism pole with a 5/8” thread for a simple way to remove and re-attach prism covers with ease.



While these innovative new survey products offer significant time-saving advantages on-site, they also allow crews to work smarter by staying out of harm’s way.

Through a powerful combination of high-quality materials, innovative measurement capabilities and greater protection, Berntsen’s line of RS mini prisms can prevent many of the mistakes commonly made on surveying, monitoring and construction sites.

Deformation Surveying With Mini Prism Angle Targets

As aging infrastructures gradually deteriorate, applied loads and other stresses to structures can lead to deformation over time. Fortunately, deformation monitoring can reveal these steady distortions in shape by measuring precisely in what way a structure is being deformed and how rapidly that particular area is being misshapen.

These types of monitoring surveys are increasingly being utilized to carefully measure and track the stability of older infrastructures and those under constant duress from applied loads and other external stresses. In addition to age and stress, structural deformation can also be the result of geological shifts, which in turn, create instability in the structures built nearby.

Typically, the types of survey projects that require deformation monitoring fall under one of the following:

Leveling – when slight movements are too small to be obvious without instrumentation.

Stressed Building Sites – construction sites where tasks such as ground compaction might need to be measured.

Stability Surveys – Both land and structural surveying where deformation can occur in manmade structures or come as a consequence of land movement.

Other uses for deformation surveying can include measuring the effects of cracks that appear on structures, large floor leveling surveys, and larger industrial measuring tasks.

How Berntsen’s Mini Prism Angle Targets Provide A Solution For Precise Deformation Surveying

Today, there are a number of techniques used to monitor and survey structural or land-based deformations––yet geodetic systems still provide highly precise measurements that normally don’t require further comparison with other independent measurements.

survey prismsFor surveyors in search of monitoring equipment capable of providing extremely accurate results over extended lengths of time while remaining robust and durable, we offer the RSMP180, RSMP280 and RSMP15 Mini Prism Angle Targets.

Featuring a 180º rotating prism component, the RSMP180 makes it possible to use the same survey point from different locations. In addition, several mini prisms can be combined with each other using an integrated connector system. This allows surveyors to make measurements in different directions while the prism remains in place––an advantage when carrying out three-dimensional measurements commonly needed when surveying deformations.

These prisms also offer convenience. Both can easily be glued to virtually any stable surface––even glass and marble facades. The exceptionally small size of the RSMP15 makes it the perfect choice to conduct long-distance, non-invasive deformation projects in especially difficult areas such as railroads and bridges. Together, they provide a sensible solution to an increasingly essential surveying task.
