At Chad, we know what it takes to achieve sub-micron precision. Part of the challenge is the attention to details during assembly. Alignment, planarity, orthogonality and calibration are major factors. Our knowledge of calibration and characterization techniques and appropriate measurement devices such as laser interferometry equipment allow us to achieve cutting-edge precision.
Our team builds and measures flatness, repeatability, straightness, perpendicularity and parallelism of stages with respect to each other and other equipment in the machine. Accuracy becomes intrinsic to the assembly by way of assembly technique, measurement and verification.
