-This page is for automation, particularly for microscope stages.+This page is for automation, particularly for microscope stages.  Most precision stages employ some sort of micrometer, 40 TPI is common.  However, you can still get reasonable precision at lower threadings.  For example, the Sherline 2000 CNC stage that I used originally is only 20 TPI (precision 1/4-20 leadscrew) but was plenty good for most operations.  Although the actual precision doesn't have to be as good, you may run into higher backlash and other issues that could make CNC planning and image stitching harder.

 These are easy to deploy and work with many existing stages. That is, they can be cost effective in that they can be picked up and then used to retrofit an existing piece of equipment like the mirror mount above. These are easy to deploy and work with many existing stages.

 Uses piezoelectric static/dynamic friction motors.  The New Focus 8095 would probably be my choice for fine positioning, roll, pitch, and z in particular.  These stages are low profile, very stable, and very precise.  Some disadvantages are that they have relatively short lives compared to conventional motors and that they might be more expensive due to more limited availability compared to more conventional motors.  As of 2012 at auction they go for about $100 for a used 1" travel unit.  Controllers appear much less often but go from $50-200 for both "network" (computer controlled) and regular varieties. Uses piezoelectric static/dynamic friction motors.  The New Focus 8095 would probably be my choice for fine positioning, roll, pitch, and z in particular.  These stages are low profile, very stable, and very precise.  Some disadvantages are that they have relatively short lives compared to conventional motors and that they might be more expensive due to more limited availability compared to more conventional motors.  As of 2012 at auction they go for about $100 for a used 1" travel unit.  Controllers appear much less often but go from $50-200 for both "network" (computer controlled) and regular varieties.

 Makes some actuators that look to be a little smaller than the Newport 860A.  Maybe stepper motors?  Haven't arrived yet.  I got a few for $40 each, a foreign seller was asking $100 each for the same units. Makes some actuators that look to be a little smaller than the Newport 860A.  Maybe stepper motors?  Haven't arrived yet.  I got a few for $40 each, a foreign seller was asking $100 each for the same units.
