Inverted BiologicalMicroscope
Brooke Clarke 2014
I found this while searching for a Nikon Plan 2x/0.05 microscope objective for my Labophot microscope. This device cost less than the going price for just the objective even including shipping it. It turns out to be an automated inverted microscope designed to look at a tray full of petri dishes. There are three Airpax stepper motors, one for Front-Back, one for Left-Right and one for Up-Down (behind front panel) movement. In The objective looks up and is coupled to an machine vision TV camera and that whole assembly moves up/down to focus. There's an arm with a lamp house and condenser system that accepts two sliders.
Here's a photo I found on line that shows the 3600 model and what may be a PC computer, monitor and keyboard, or it may be a custom electronics package?
The major components are mounted on a 27" x 16" wood base. There is an arm mounted at the rear of the baseboard that holds the power supply, lamp controls, lamp house and condenser assembly. I suspect this came from a commercial microscope. If you know which manufacturer/model let me know. The mechanical stage is mounted to the front of the baseboard and consists of the X-Y-Z stage and the optical assembly.

Objective & Camera
The objective image is turned 90 degrees by a mirror (maybe a prism?) and feeds an MTI CCD72 TV camera.
Came with cable but not controller, which is on order.
