Modeling Gold Nanorods Solution as lens in Zemax

Hi! I have a question about modeling a gold nanorods solution. This solution has a  Molarity of 2.5 (nM) and a Molar extinction coefficient of 9.68*10^8 (M^(-1)cm^(-1)). The optical path is around 6.33 mm.

I am modeling in non-sequential mode. Following the guide on this post:, I tried to modify the material water within Zemax by changing the transmission.

The transmitted intensity is given by Beer's Law and is roughly 0.2. However, when I changed the transmission from 1 to 0.2 at the wavelength of 808 nm, the detected intensity does not change compared to the default water. Can anyone help with this issue? Should I change anything other settings to model the gold nanorods solution? Thank you so much!

Hi Chang,

Please make sure you have polarization checked in the ray trace control.



Hi David,


That solved my problem. Thank you so much!
