Off axis correction of Biconic surface and Two angle source

I'm working with imaging system. I want to focus light at the center of detector. I used Two angle source so when Detector placed at 45 Deg to get the irradiance of source, there is shift in high intensity on detector to its edges. And also when placed tilted Biconic surface(It has two radii), there also got shift in intensity on tilted detector. . But I think its due to off axis effect and have no idea how to solve it.  Could you please help me to solve this

Thank you

Hello all,

The image I got after tilting of detector about 45°is attached here where the intensity is shifted to lower edge . Could someone help me about this . I expect uniform distribution. Is it beacuase of divergence angle of source ?

Thank you,
