Mini prisms are an essential component of any surveying operation. They are attached to prism poles or static surfaces to act as a focal point for a wide variety of electronic distance measuring equipment – many of which you can purchase direct from our online store. Mini prisms offer many benefits to professional surveyor, including the highest accuracy over a maximum range.
Our mini prisms benefit from an anti reflex coating, which allows them to operation effectively even in the most extreme environmental conditions. These coatings help to trap light within the glass prism, helping you achieve readings of the highest quality. A laser beam targeted at these prisms from a total station, laser level, or theodolite ensures precise measurements for your project.
Theodolite and total station lasers enter a mini prism at the speed of light. At this speed even the slightest obstruction can cause inaccuracies in measurements. Corner cube prisms, commonly used on sites, cause the light beam from your EDM devices to take longer entering the glass prism. This affects the prism constant and requires all measurements to be offset accordingly. Models with a circular design can help reduce this offset, delivering great prism accuracy.
In addition to our stock of mini prisms, we also have a selection of mini prism accessories to make life easier for you on-site. These include quick change adaptors, as well as prism pole attachments and sets, manufactured by some of the surveying industry’s biggest names.
