Dear List Members,

Does anybody know a robust hardware autofocus mdoule that can be used on
Olympus IX70.  We plan to use it for TIRF and mutliwell time-lapse imaging.
The software focus is very time consuming.  We are currently use Metamorph.
We can also try to set up microMangager if necessary.  Thanks in advance for
any input information.

Best regards,
Sheng
