Using the L-shaped bar to attach the filter wheel to the focus stage

Menu

Step 1 of 4

1. These screws (and there's a third one to the right, not seen in this picture) hold the L-bar to the stage. And no, they aren't screwed all the way in yet. They should be flat with the bar.
2. This is the focus encoder (attached to the big thing to its left, which is the motor-controlled screw). The arrow indicates where it's supposed to be when the whole assembly is complete.
3. A limit switch for the encoder.

Step 2 of 4

1. Seen from a different angle. Here are the other three screws that hold this bar to the stage. You can also see the three from the previous picture down below them (again, not screwed in all the way yet).
2. The stage. When properly set up, the bottom half of the red piece moves back and forth to adjust the focus. See the overview page for the whole image.

Step 3 of 4

1. Now actually putting the filter wheel plate on the L bar. The arrows indicate what lines up with what, and the rest is just screwing it all together.
2. Just in case you're confused, this black thing is the L bar from before. But let me clarify something a little bit: it's only L-shaped at the ends. There's a piece in the middle that sticks up so you can bolt it to the focus plane. Unfortunately, we don't have any pictures of it, but if you take it apart it should become obvious what's going on.

Step 4 of 4

1. Here the screws are in their proper places. You can assume there's a 1b somewhere in the background, left of the Allen wrench.
2. Click on the wrench to see just how much clearance it has. This is a special wrench, cut short for the job.
