[Raytrace] TCT (Tilted Component Telescope) designs

[JulesFran@aol.com]

Hello list,

I'm new to this list and have a few questions:

Has anyone modeled a four mirror TCT design with OSLO Lt? I would like to use 
this as a starting point to evaluate a few designs I have been playing with. 
Up til now I've been using David Stevick's software which is wonderfully 
simple to use but doesn't have the horsepower I need to go to the next level.

Has anyone modeled a mirror profile using Zernike polynomials for input into 
a raytrace program? What I would like to do is use the actual test results 
from a mirror profile analysis and use this to evaluate the system Strehl 
ratio of a final "as built" TCT.

Regards,

John Francis
