Re: Conic constant temperature invariant?

thank you very much for the answer. Can you also tell me some literature
where I can find information about the thermal analysis of optical elements?

Greetings

Florian

Florian:

You can find some info in Chapter 39 Thermal Compensation Techniques
by Phillip Rodgers and Michael Roberts in Hdbk of Optics Vol I
They talk about the active and passive athermalization of optical
system.

For thermal analysis of optics mounts see Paul Yoder's book on
Mounting Optics in Optical Instruments
and also Chap 9 by Victor Genberg in Hdbk of Optomechanical
Engineering by Anees Ahmad
Genberg and Co also have a book on thermal modeling FEA of optical
systems

For optical design specifics look up athermalization in Applied
Optics, JOSA A&B and SPIE Proceedings

Thanks for asking the question, I had not thought about this and had
to think back to my calculus of conic section and ellipses &
hyperbolas.
Right now I am not sure I agree with the answer given yet, can you
tell us more about the rest of the system?

Are these mirrors in a telescope or hyperbolic lens surfaces?

Thanks,

Michael
