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.
