442nm (Violet-Blue)
Model 4210N

Power Supply Model 4200PS
and User Manual

This laser has a start up problem, but the tube still has lots of cadmium and appears to be fine. I'm not a laser expert, but there is lots of HECD laser information on the web and from everything read, observed and some initial measurements, the problem appears to be in the power supply or it's control circuit. I planned to repair and then sell the laser, but have never found the time so, until I do and list it for much more or it's sold, it's being sold "as is" to anyone that doesn't mind repairing it them self.

'Scanning Transmission Electron Microscope' or 'Scanning Tunnelling Electron Microscope'

I believe this is a 'Scanning Transmission Electron Microscope', but STEM is also used for 'Scanning Tunnelling Electron Microscope' and I know little about such things so not really sure which it is or if both are perhaps basically the same thing. I would like to know more about this item, where information on it or on any of its components may be found, if it should be left intact or should simply be scrapped for useable parts and would appreciate an Email if you're knowledgeable about such things. Also Email if interested in purchasing this STEM or any of its components. There are several web sites describing the experience of building one's own electron microscope, but having this STEM would make the task much easier for others wanting to do something similar.

Transmission Emitter?


I was told that this is the electronic portion of a STEM system, complete with emitters & detectors, and only needs the mechanical components, like specimen chamber, vacuum pumps, etc., to work again. Perfect for someone wanting their own electron microscope who can build the mechanical portion.

This is a second microscope display unit in a floor stand which has a
bezel designed to accept a film or digital camera for recording images.
