WebStray light can lead to unwanted bright spots, which reduces image contrast and a system’s dynamic range. In the case of #smartphone cameras, stray light is a common culprit for blurring and ... WebI am using Zemax for spectrograph Stray Light analysis, but I got some issues with the grating model. I used two objects (the front object is rectangular Volume, the rear one is Diffraction Grating). When I tried to find the strongest scatterings, one path is shown as the below figure. The light bumps several times within grating.
