Hello,

Apologies for the delayed response. I would recommend posting your question about exporting Zemax files in the Optics forum for the best guidance( Optics) 

Have you came across this example?Tech Tip Tuesday: Thermal camera simulation | Zemax Community

Also, you can get more information on creating custom source spectrum here :Creating a custom source spectrum for an FDTD source – Ansys Optics

Thanks
