Mating an axially symmetric lens to a retaining ring
Mating an axially symmetric lens to a retaining ring
(OP)
A very frequent problem that I have that is currently unsolved is the following:
I import a lens system from Zemax in STEP and then have to build a mechanical assembly around it. This generally involves placing the lens in a tube, often with the lens being held in by a retaining ring. Something similar to this is shown on the ThorLabs site in the cross section picture: http://thorlabs.com/NewGroupPage9.cfm?ObjectGroup_...
My question is, how do I mate the lens with the retaining ring? Currently I mate them concentrically and then move them very close to each other and fix the location, but this is a very messy approach. Selecting the lens surface and the closest circle from the retaining ring and mating them as coincident is not something Solidworks considers valid.
Thanks.

Now you're just showing off! Very cool.
Thanks :)

What I often do with lens spacers and clamps is turn on the profile sketches of the lens and of the spacer/clamp. These should mate nicely.
