5.7 Adjusting the illumination
To make sure that perfect image results are achieved during microscopic observation,
it is important that the direction of light of the microscope is optimised. The following
components of the transmitted illumination can be adjusted according to the application
requirements.
Aperture diaphragm
The aperture diaphragm is used to find the very best compromise between contrast
and resolution for the microscopic image.
To open and close this diaphragm you have to operate the lever [1] located at the
condenser.
Colour filter
The colour filter slide has one round aperture [2]. If needed, the supplied blue filter [1]
has to be inserted into this aperture. Subsequently the filter slide must be put into the
slot on the top of the condenser.
