ZEISS PRISMO® ultra
Top end model of ZEISS PRISMO® series with the highest level of accuracy
ZEISS PRISMO® ultra was developed to meet the needs for extremely high accuracy in measurement, such as in research and development for high precision parts and calibration inspection of reference gauges.
Features
Achieving highest level of accuracy
High accuracy at the level of E0, MPE = 0.5+L/500 μm is achieved by mounting an ultra-high resolution scale and utilizing a variety of technologies to minimize the impact of temperature changes on measurement results.
Ultra-high resolution scale made of Zerodur®
The scale with the highest resolution 0.02 μm in ZEISS PRISMO® series is mounted on each axis.
Moreover, Zerodur®, a material with an extremely low thermal expansion coefficient, is used for the scale to minimize the impact of changes in the environmental temperature on the accuracy.
Advanced CAA correction technology for high accuracy
Fine CAA, a method for correcting guide straightness errors by splitting into 64 fine grids, is used.
In addition, by means of “tensor calibration” to determine the deflection of stylus and calibration sphere by probing the same location multiple times while changing the measuring force in calibration, deflection error is removed from measurement results to achieve high-accuracy measurement.
