The adapter plates are suitable for the ZEISS VAST XTR gold sensor. This sensor has an integrated rotary axis, which always aligns the stylus in the direction of the feature to be measured. ZEISS VAST XTR gold is based on the design of the ZEISS VAST XT gold. The VAST navigator and VAST performance functions are fully supported by ZEISS VAST XTR gold. The sensor is an expert system that suggests to the customer the optimum measuring speed for the desired accuracy. The VAST XTR sensor and the adapter plate form a technical unit. The integrated chip allows for advanced software and machine functions. New controllers such as the C99m controller can fully exploit the potential of original ZEISS adapter plates.
