PY004 High Load Pitch Yaw Platform
Chapter 4 Specification
4.1 Specifications
a
The minimum incremental movement for manual stages is based on half a
graduation of the micrometer scale.
b
Motorized stages only.
c
The load capacity when the stage's base is mounted on a horizontal surface. The
max load capacity is different at certain points of the platform. See spatial drawing
Fig. 4.1 for specific load capacity information.
d
For motorized stages, the pitch axis actuator could wear out after approximately
5000 cycles if used continuously at the max load.
e
The load capacity when the stage's base is mounted on a vertical surface. The
vertical max load will depend on the stage orientation, the positioning of the load on
the top platform, and the distance of the load from the platform. The load data
provided is approximate and meant as a guide only - see Fig. 4.1. overleaf.
