PURPOSE OF THE TRIBRACH
The tribrach enables surveying equipment to be levelled and centred over a benchmark. To achieve accurate measurements, the tribrach must ensure a firm connection between the tripod head and mounted instrument.
The stability of the tripod and tribrach is the primary influence on the reliability of measurements. The critical factor for accuracy is the provision of a stable platform for the instrument; if the base is unstable the measurements will be unreliable.
 
FEATURES OF THE TRIBRACH
Our tribrachs are designed to operate reliably even in extreme temperature, humid and dusty conditions. In all situations, the maintenance-free foot screws ensure a movement that is always smooth and free of play.
The support area of the tribrach is matched precisely to the base circumference of Geosystems equipment. This provides extremely accurate forced centring.
Even after a long operating life, the quality and precision characteristics are maintained.

ACCURACY OF THE REFLECTOR
A circular prism is manufactured by cutting the corner from a solid glass cube. This creates three mutually orthogonal reflecting surfaces that reflect any light rays back towards their source.
 
ANGULAR BEAM DEVIATION
The angular difference between the entering and exiting beam is known as Angular Beam Deviation. A high deviation significantly reduces the returned signal strength and hence the measurement range.
After manufacture, each prism is measured by Zygo inferometer to determine its beam deviation.
 
REFLECTIVE COATING
The prisms have a copper coating on the reflecting surfaces. Copper offers a very high reflectance of infrared beams. Being robust and resistant to corrosion it has a long useable life.
