WebNov 3, 2024 · Figure: Out-lens Method and In-lens Method. The higher resolution is the in-lens method, which shortens the focal length, but it cannot be used if the sample is affected by a magnetic field. In that case, the out-lens method, which is less affected by the magnetic field, will be used. WebAug 3, 2024 · Using an old episcope projector, ... It also depends on the focal length.
