This is a hobby for me, so any kind of commercial software is out of question. I have a background in mechanical engineering and only know the basic photometric and radiometric principles. Therefore there is much I don’t understand. To use the ImageJ I should have grayscale images representing...

I have the datasheets for both the LED and the diffuser so all the info needed should be available. Are there any good and free ray tracing software out there? All I can find is a few software for lens design. Could the calculation be done as a stochastic simulation in some mathematics software?

I need to calculate irradiance in a system shown on the image. There is an infrared LED on the left and a diffuser in front of it. I need to calculate irradiance at a certain distance after the diffuser. I think I first have to calculate irradiance at the diffuser. Then multiply it by the...
