I have a fiber source with laser radiation illuminated at an angle 40 deg from horizontal. So, obliviously the output image would be an oval shape. And I am using merit wizard for rms spot and also a REAY operand to get constraints on rays to fit in the detector. Since the source is at an angle we can cannot focus all the rays so the intensity/irradiance profile on the detector is a slope. But I need to know whether there is any merit operands to get a constant line for the intensity/irradiance profile?
