Hardware and Positioners - Frequently Asked Questions (FAQ)
 What is meant by thread pitch?
 I mounted one of your 07 TLC 204 linear translation stages on a 07 TSR 204 "L" bracket for vertical travel but noticed that the top of the stage drops down when loaded and is no longer in contact with the micrometer. How can I fix this?
 How do I make an in-line refractive beam steerer using your 02 PRW-series wedge prisms?
 When is it better to use a flexure mirror mount over a standard kinematic mount?
 I want to be able to mount one of your 07 MAT 703 Fine Touch thumbscrew drives on to one of your 07 TLC 224 translation stages. Will it fit?
 I noticed that resolution specification for your manual actuators differ between the micrometer and thumbscrew drives in that the specification for the micrometer is postulated with the term "incremental mark". Is this really the best resolution the drive is capable of?
 When should I use a round-tipped actuator vs. a flat-tipped actuator?
 When should I use ball bearing vs. crossed-roller bearing translation stages?
 I purchased two of your 07 TXC 724 translation stages to make an xy translation stage, but can't find the OrthoPins.
 Can I motorize one of your 07 MHT 225 or 07 MHT 227 kinematic mirror mounts?
 Can your 40 X 40-mm center-drive translation stages be motorized?
 I see that you have 65X65-mm translation stages with 1 inch (25 mm) of travel ie.
The 07 SSS 224/A. Can these be motorized?
 I have one of your 07 TLC 224 65X65-mm, 13mm travel translation stages and one of your
07 MAM 704 micrometers with 25 mm of travel. Can I mount this to the stage to give it 25 mm of travel?
 Do you have any side-drive motorized translation stages?
 What is a "Flexure" Positioner?
 Why would I want to use a Flexure Based Positioner?
 What are Piezoelectric Actuators?
 What is the difference between piezoelectric actuators with and without position feedback?
 How can the autoalignment piezoactuator controller help me?
 How does the autoalignment piezoactuator controller align a fiber to a device?
 What is the main advantage of the autoalignment piezoactuator controller?
 What specific functions does the autoalignment piezoactuator controller provide?
 How do I align a fiber to a device optimizing five or six axes?
 What about interaction between axes?
 How useful is the CRT display?
 I wish to automatically align a fiber into and out of an integrated optical device.
 I want to permanently attach fibers. Can the autoalignment piezoactuator controller follow relative movements during a bonding process?

 Do I need to provide a computer?
 When should I consider using a piezoelectric controller having feedback?
