Cameras & Microscopes
| It is reasonable to assume that a camera
attached to a microscope will reproduce what is seen when looking into
the eyetubes of the microscope (A). But indeed, this is not the case. The
main reason is that the microscope FOV or Field of View is round,
and the output of cameras are square or rectangular. The result is
either the circle inside the square or the square inside the circle. A
majority of microscope users prefer the square inside the circle (C).
However, with this arrangement, one will not be able to see the outer parts of the round FOV outside of the cameras rectangle but the majority of the image will be seen however cropped and somewhat magnified within the cameras field of view. Below are examples of the varied results one can get with microscope camera adapters. Using the zoom function on your camera with "vignetted" setups (B & D) may allow the user to "zoom" past the vignette area. However, one will get still more magnification and less of the microscopes round FOV. |
