Fiber coupled LED

modelling a collimated light from a fiber coupled LED using and an achromatic doublet. I will like to see the effect of temperature on the collimated light. Thanks in advance.

Hi there,

Would this be a conjugate heat transfer simulation, with radiation enabled?

There is no fluid present in this situation. heat sink of the LED, a fiber coupled LED, an achromatic lens placed at some distance equal to the focal length of the lens.
