I can't understand: the ray intensity in "polarization ray trace" can be more than 1 ?

Hi, My friends,


I am doing a ray polarization ray tracing in a Wollaston Prism model, the initial ray intensity is set to 1, but I found the insensity before the Prism surface becomes 1.025869078071, that means the ray energy is increased, this confused me. Can you help? Thanks!


The following is some polarization ray trace information:

Hello Guangjun,


This could be a couple of things. I have seen this if there are negative thicknesses in the system when you are not in mirror space. Make sure that after a mirror the thickness switches signs. 


Also, it depends what the material is on that surface. It is possible that the material you are using has an imaginary index (k) greater than 0, meaning it is an 'amplifying' material based on this definition. 



If this does not help would you be able to post your file here or open up a MyZemax case with us?

Thanks, Kaleb,


I will check the thikness and material.
