Abstract
The invention relates to an environmental cell for use in e.g. an electron microscope. The environmental cell shows an aperture (15) for passing the beam produced by the electron microscope to a sample (6) placed inside the environmental cell. The environmental cell according to the invention is characterized in that a part of the environmental cell (14) is transparent to secondary radiation such as back-scattered electrons or X-rays. This enables the detection of this radiation by a detector placed outside the environmental cell and thus a much simpler construction of the cell.
