One last BeamScan for sale. This one works but is missing the actuator for the diffraction grating and the arm for the shutter flag. I'll include a 12V Ledex rotary solenoid that should not be too difficult to kludge in for the diffraction grating. The shutter actuator is there, just needs a lightweight arm with a bit of black aluminum added for the input shutter. I've attached a picture of the system and one of the scanhead showing the missing parts. The last picture is of a complete scanhead for reference.
