QNP3 Hardware Manual
Overview
1.2. Environmental Specifications
W A R N I N G : Do not expose this product to environments or conditions outside of the listed
specifications. Exceeding environmental or operating specifications can cause damage to the
equipment.
The QNP3 stages are true nanopositioners. To achieve superior performance at the nanometer level, a very
well controlled environment is essential.
describes the minimally acceptable environmental
specifications for normal stage operation. Better control of the environment will yield better system
performance. Contact Aerotech for more information regarding your specific application and environment.
Humid environments are more detrimental to piezo actuators when they are held at high voltages for long
periods of time. For static positioning applications it is recommended that QNP3 stages be configured to
keep average voltage as low as possible to achieve maximum lifetime from the internal piezo actuator.
Operation in gaseous environments other than air may affect the rated operating voltage of the QNP3 stage.
Consult the factory for details.
W A R N I N G : Using the QNP3 in environments with relative humidity greater than 60% may
require a reduction in travel and max voltage to ensure a long operating life.

Minimum Acceptable Environmental Specifications
Ambient
Temperature
The optimal operating temperature is 20° C ±2° C (68° F ±4° F). If at any time the
operating temperature deviates from 20° C degradation in performance could occur.
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Humidity
Operating: <60% RH
Storage: <40% RH, non-condensing in original packaging. The stage should be
packaged with desiccant if it is to be stored for an extended time.
Altitude
Operating: 0 m to 2,000 m (0 ft to 6,562 ft) above sea level
Vibration
Floor or acoustic vibration will affect system performance. A quiet environment,
isolated from ground vibration is recommended for optimum performance.
Protection
Rating
The QNP3 stage is designed to operate in laboratories and clean production
environments. Operation in heavy dust environments could lead to contamination
inside the stage and degrade performance.
