Imaging aperture is too large

Hi, the imaging aperture (green lines) is too large to be realistic. Light can not leave the specimen under these angels because it is limited by the total reflexion angle. The limit is a beam in the specimen, which is parallel to the glass surface, which will lead to a beam of the total reflexion angle in the glass body. I would suggest to limit the green imaging aperture and make the tip of the green beams a little bit flatter to match the reality of the different diffraction indices. --Ulfbastel (トーク) 15:31, 20 November 2019 (UTC)
