The IES TM25 standard for ray files has been out for years but we are still waiting for Zemax to allow these files to be imported in to optical models. Osram only provides ray files bigger than 10M rays for its LEDs in TM25 format so it is definitely needed and its hard to understand why there has been such a delay. Having read the TM25 standard it would take very little development time to implement.

Hi Andrew
Thank you for sharing this feedback. It is certainly valuable.
I will add a feature request and will make sure our product team have a close look at it.
Kind regards

Hi Andrew,
in case you don't want to wait for ZEMAX to implement it.
a) Download the ttr format instead and create any number of rays following section D of

or
b) drop me a note with details of your case
Best regards,
