Other fault events
•
I can see a distinct grid and a bright, luminescent area in the live image
−
The Auto Focus signal (wavelength 850 nm) is not being blocked. This problem can be resolved by
inserting the IR barrier filter (BG 39 or BG 40) in front of the camera.
•
The focus cannot be found.
−
The Auto Focus beam splitter is not in the beam path.
−
The Auto Focus is not switched on.
−
The surface structure of the sample is too rough / diffuse, preventing any Auto Focus signal from
being detected.
•
The Auto Focus starts to jump between two planes when moving the sample.
−
The structure being focused upon may be parallel to the signal structure of Auto Focus. Rotating the
sample or the Auto Focus sensor on the microscope should permit correct focusing of the sample.
•
No focal position can be found when fluorescence is used.
−
It is not possible to use the Auto Focus function when fluorescence is used.
•
No focal position can be found when DIC/C-DIC is used.
−
C-DIC cannot be used in conjunction with Auto Focus.
−
Use of Auto Focus may be limited with DIC applications.
•
The Auto Focus does not function if the reflected light brightfield reflector module is swiveled into
position.
−
The grey filter must be removed from the reflector module.
