A nice piece of Gear....
Since everyone here is always looking for tiny gear, I thought I'd post a pic of one of my favorite toys. I have four of these in my collection. These are late 1980s R2 scan heads by Laser Systems Development Corp. I do actually use these from time to time. The whole unit is aluminum. It is precision TIG welded at the corners. Just attach to a large frame ion and go.,.... Attachment can be easy if your Ion has a standard 1"-32 Threaded port on the front, with a small plate setting underneath to take the weight of the bezel of the laser. On they can set on Standoffs on a baseplate. You could feed say four of them from a Prism, for RYGB abstracts. Back then the Ledex shutter was not considered too slow.
The beam comes in through the concentric tubing, which doubles as a pivot.
Always wanted one as a kid in 1990 or so... I finally obtained them them much later then I expected.
Add a pair of scan amps, and your basic Ion laser, and this is actually quite a capable, practical, projector.
