Is there an IOR option for transmission in StandardSurface shader?

Is there an IOR option for transmission in StandardSurface shader?

I'm using Arnold 5 and Maya.
I'd used Soecular IOR but for a glass with high IOR like lens, when I put the specular to more than 2 it's just create a transparent metal surface.

When I enter a high value (3.0) using the Glass preset, I get the following result. Can you post your result and settings?

Hi Lee,
Thanks a lot for your aswer, It's reflecting too much with specular ior.
Is there away to just increase ior for transmision?(like redshift)

Hi @Sina Mehralinia! Maybe you can use the coat just like the specular and use the coat ior to balance the specular / transmission ior with the specular and transmission amount that do you need.
