Does anyone have an real Sapphire glass catalouge that I could use for
Code V? I'm have issues evaluating Sapphire at -55 degree C (it
refused to do so unless I give it dN/dT values which I can't find
anywhere).
Thanks |

This is one source of data I've used in the past - it reports:
dn/dT 13.1 x 10-6 at 0.546 microns
Any use?

Just tried it. For some reason CODE V wants me to define dN/dT for all
my specified wavelengths :(
If I use 13.1 microns it goes crazy at -55. Thanks anyways though I
appreciate it. |

Sapphire is opaque at 13.1 microns. Ref:http://www.valleydesign.com/sapppic.htm
Sorry! Try to find another material.

Ok I figured it out. It wasn't Code V. It was me. I'm an idoit  I
had CaF2 as a glass and it doesn't respond well to temperature
changes.
Thanks for the help. I ended up using 13.1 for my dn/dt values on the
Sapphire. |
