ZEMAX

[xnaren]

Hi everybody,
i need help from zemax users. i am using light tools software. i planed to do a fresnal lens in light tools but i don't have enough information to design it. when i asked a manufaturer regarding the info about the lens he gave me a list of commands by which we can create it in zemax. if some one who uses zemax can use those commands and export the lens to igs, step files... i really appreciate it.
thanks in advance

here is the commands to create that lens

Hi,
I imported this into zemax and then output into an IGS file.
Let me know if this worked and if I can help further.
We make custom prototype optics and standard parts.
I'll send this file to you, e-mail me at the address below.
Good luck,
