What is the importance of mini prism in Surveying?

Mini Prism offer a high positional accuracy because it is small size. It has also a built-in levelling bubble and is supplied with an attachable spike. With this arrangement a point can be measured with very high precision.

Prism Measuring Accuracy

The range of a prism results from, among other things, its coating and the glass geometry. Measurement errors occur frequently at close ranges when prisms without anti-reflex coating are used, as the front of a prism always directly reflects a certain percentage of a signal. Errors occur in the use of prisms without copper coating on the back side when moisture droplets accumulate or the prism becomes foggy.

High standard quality prisms have a special coating on the reflective surfaces – the Anti-Reflex Coating, and a copper coating on the reverse side. Without these, the range of distance measuring, ATR and Powersearch would be reduced by up to 30%. The workmanship and the durability of the copper coating are decisive for a long life.

The glass dimensions, the position in the holder and with it the areal orientation, are important for measuring accuracy.
