Hi @KRD,

Are you asking about vignetting in general or is there something specifc to your analysis that we should notice from your screenshot?

If you are asking more generally about vignetting, I can suggest this article from Edmund Optics:

https://www.edmundoptics.co.uk/knowledge-center/application-notes/imaging/sensor-relative-illumination-roll-off-and-vignetting/

Otherwise, please clarify what “type” of vignetting you are talking about and the kind of imaging system you use.

Take care,

David
