Beer Lambert law

Please login with a confirmed email address before reporting spam

How can I model a simple beer lambert law where Intensity of ray decreases due to attenuation but the ray directly passes straight from the material ? Also how do I input my own equation in model i.e, I=I0*e^(-alpha * T) where alpha is the attenuation coefficient ,T is the thickness of the material and I0 is the initial intensity of ray.

Someone please help.I'm stuck from past 4-5 days .
