1.1 Description of the MicroBlock 3-Axis Flexure Stage

The MicroBlock
has been developed to meet the stringent requirements associated with aligning fiber
optics. The top-mounting platform can be adjusted along three translational axes —
x, y, and z — with respect to the base. It features a nominal working platform height
of 62.5 mm and provides a common optical-axis height of 75 mm.

1.2 Drives

The MicroBlock is available with a choice of drives, a differential micrometer drive
(MBT616D) and a thumbscrew drive (MBT602).
The differential micrometer has 4mm of fine position adjustment with 0.5 mm travel
per revolution, and 300µm of ultra fine adjustment, with 50 µm per revolution making
it ideal for aligning single-mode fibers. The simpler thumbscrew, fine-threaded drives
for use with less demanding multimode fiber-optic systems provide 4 mm of fine
position adjustment with a 500 µm travel per revolution.
