After entering the objective, light then passes through the partially silvered mirror (or in darkfield, through the elliptical opening).
WebNov 12, 2024 · If the tertiary objective is tilted more than 18.2 degrees, in our case by 30 degrees, one can see that it cuts into the cone of light of the secondary objective (light blue, Figure 1—figure supplement 1C). Thus, the light that can be coupled in at the critical angle occurs now at an opening angle of 60 degree at the secondary objective ... WebApr 14, 2024 · Inspired by the anatomy of scallop eyes, neuroscientists at the University of Zurich have developed an innovative objective for light microscopy. The new objective uses mirrors to produce images, enabling high-resolution imaging of tissues and organs in a much wider variety of immersion media than conventional microscope lenses.
