Tolerancing group of optical elements


The tolerancing wizard applies to single surfaces and single optical elements. However, in some situations the optical elements are mechanically coupled, like in the case where several lenses are mounted in a tube. During assembly the tilt of the tube translates into tilt of the lenses therein contained.

How can I apply decenters and tilts to groups of optical elements? I suspect that a coordinate break before and after the group could lead to a possible solution, but would like to know the default/best way to do it.

Thank you!

Hi Jonsaz

 I added the operand manually, say surf1~surf2~surf3 as a unit, just set surf1= 1 and surf2= 3
