1.2. Accuracy and Temperature Effects
Aerotech products are designed for and built in a 20°C (68°F) environment. Extreme temperature
changes could cause a decrease in performance or permanent damage to the stage. At a minimum,
the environmental temperature must be controlled to within 0.25ºC per 24 hours to ensure the stage
specifications are repeatable over an extended period of time. The severity of temperature effects
on all specifications depends on many different environmental conditions, which include how the
stage is mounted. Contact the factory for more details.
The thermal expansion coefficient of the encoder scale is 3.25 ppm/°C. Travel will increase or
decrease at this rate as the temperature of the encoder scale temperature deviates from 20°C (68°F).
The accuracy specification of stage is measured 25 mm above the table with the stage in an
unloaded condition. The stage is assumed to be fully supported by a mounting surface meeting or
exceeding the specification in Section 2.2.
