Average Reviews:
(More customer reviews)The Proxxon KT70 is a great XY table. I have purchased two of them so far, for use as part of the Nano Gigapan project to allow us to take high resolution mosaiced images under microscopes.
You can take the knobs off and couple them to stepper motors fairly easily, and thus have an automated xy stage for a fraction of the price of equipment designed for microscopy.
The KT70 moves 1 mm per turn of the handles, and a 115x microscope has about a .75 mm field of view, so there is plenty of precision and accuracy in the KT70 for this purpose. In fact, the KT70 has 20 hash marks per revolution, so each hash mark is 50 microns. From my measurements the table has the accuracy to repeatably hit these marks.
That does point out one issue for Americans - everything is metric. 50 micros = 0.0019 inches - about 2 thousandths.
If you google 'Nano Gigapan' you'll find our project, along with examples of using the KT70 in scientific applications.
