2UUL MC6558 MICROSCOPE

The 2UUL MC6558 — a trinocular stereo zoom microscope on a pillar over a wide flat base plate, with the green anti-reflective coating visible on the eyepiece optics. A stereo microscope has two separate optical paths, which is what produces real depth perception. That is the whole reason board work needs one: you are judging how far an iron tip is above a pad, and a single flat magnified image cannot tell you that. Coated optics matter more on a logic board than on most subjects. Solder mask and metal shield cans throw glare straight back up the optical path, and every uncoated air-to-glass surface adds another internal reflection on top of it. Coating cuts that scatter, which is the difference between reading a pad and guessing at it. It takes a camera on the third port, and it comes from the same maker as most of the hand tooling on the bench — so the eyepiece caps, lamps and mounts in the 2UUL range are built to fit it.
