Some non-CNC microscope chassis may be easier to mod for CNC control. For example, the Olympus BHMJ is a boom mount, which can be easy to re-mount with a stage. | Some non-CNC microscope chassis may be easier to mod for CNC control.

+ | Things to consider: | ||
+ | * What resolution do you need? Likely your lowest magnitude objective will drive this | ||
+ | * Consider how camera RGB pattern will effect resolution | ||
+ | * I use 4x resolution to compensate | ||
+ | * How many bits do you need? Most cameras are 8 bit, but 12 or 16 bit will provide better dynamic range | ||
+ | * Do you have low light requirements? | ||
+ | |||
+ | For Linux software, as of Nov 2017, I believe the MU800 is the only camera with V4L support in Linux (also noting there are MU300 and MD1900 drivers not in mainline). AmScope/ | ||
