Image Acquisition
pÜ~ÇáåÖ=ÅçêêÉÅíáçå=
Activate this function if you notice, e.g. with bright-field images, a reduction
in image brightness, caused by the optics, at the image edge. For this
calibration process make sure that the camera is viewing a completely empty
image. To ensure that this is the case, move your sample on the microscope
completely out of the field of view.
Shading correction to improve image quality
In microscopy, numerous side effects can have an undesirable influence on
image quality. Dust and particles in the beam path, for example, can leave
dark spots in the image, and, under certain conditions, diaphragms and optics
can cause slight shadowing that increases towards the image edge, due to
unavoidable physical effects.
For all AxioCam models it is possible to acquire a shading reference image and
apply this automatically each time an image is acquired. On the camera
property page
General
you will find the
Shading Correction
button. This
can be used to trigger the acquisition and saving of a shading reference
image.
If you are using a motorized microscope or a microscope with an encoded
nosepiece, it is possible to acquire a separate reference image for each
objective. These images are then applied automatically for the objective that
has been selected.
Procedure for generating objective-specific shading correction
