Hi all,
We have some (fairly new) ISSCO brand Microscopes. They were expensive ones with in built light sources, etc, which we bought for our Senior Students. It seems that on a couple of them, the moving stage seems to have "slipped a cog" and will no longer raise up high enough to focus. If you manually pull it up and stick a peg under it it can be focussed, but not by turning the knob. Has any body else had this problem with these Microscopes? Is there an easy fix (besides the peg)
You probably should ring ISSCO as they are only new. We have had lots of different ones from them with no probs. They would be covered under a guarantee? If not, they would still be the ones to ask how to fix.
Ian, if they are no help (ISSCO), remove the screws at the top & bottom of the vertical thread on the neck of the microscope. Drop the moving lense stage to the bottom of it's travel, wind the focus adjustment all the way for down until it stops then feed the vertical thread back through and tighten screws. Unusual for them to start stripping out the thread at this early stage! Hope this helps mate!
