Tested, see photos. Zooms 6-50x. Illuminator is tested and works great. Optics are fairly clean and clear.
This stack was formerly mounted to a high vacuum chamber (outside of a glass viewport) and still has the X/Y tilt and some fine Z focusing control built-in. The viewport is also included and has some metal mesh screen on it to prevent high energy photons from escaping (this was previously mounted on an XPS system). Knife edge is in great shape.
Used, see photos.
Power plug is custom: do not plug that into mains AC power outlet - it functions with 2A and a compliance voltage of like 8V. Check bulb for exact specs before powering.
