4.4 System Stability

The MicroBlock has been designed using traditional precision engineering techniques
combined with flexure technology for precise, stable and frictionless motion. Extreme
care and precise matching of tolerances and components coupled with the fine thread
adjusters or differential micrometer drives, ensure that MicroBlock provides the best
possible positional accuracy and stability.
The threads used for the drive screws are very finely made with the correct clearances
and lubrication. The lubricants and choice of material employed in the design and
manufacture are critical to the performance and stabitlity of the MicroBlock. Changing
the thread lubricant may adversely affect the performance of the whole system.

4.5 Mounting Equipment to the Moving Platform

Caution
To avoid damaging the internal flexures:
The weight attached to the moving platform must not exceed 1 kg.
Do not apply excessive forces to the moving platform.
When mounting devices to the stage, do not use screws which protrude into the
internal mechanism.
Thorlabs manufacture a variety of fibre chucks, holders and fixtures to fit the
MicroBlock stage, which are mounted on the top platform.

4.6 Transportation

Caution
When packing the unit for shipping, use the original packing.
If this is not available, use a strong box and surround the MicroBlock with at
least 100 mm of shock absorbent material.
