Detector rectangle problem

Hi,

I have created two Detector Rectangle objects to check the beam shape at different planes. I set them with different size and pixelization (one squared and one rectangular). However in the detector viewer i keep seeing a much bigger detector area, always with X and Y coordinates spanning from -90 to 90 for both the axis and detectors. Moreover none of them has that dimension. Why do i see such an effect?

Thanks,

Marco

Sounds like you may have the detector set to display Radiant Intensity (which is power per unit solid angle):

By default, the detector will then display results from -90 to +90 degrees.

Instead, you may be more interested in the Incoherent Irradiance (which is power per unit area).

Regards,

Jeff
