25.4 mm Mini Prism with Plastic Holder and Bag 1

Optical Coatings

Our mini prisms benefit from an anti-reflex coating, which allows them to operate 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.

Improved Prism Constant

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 to enter 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.
