Problem: The acquired image is not in focus

Possible cause

The microscope was not focused

on the sample.

The parfocality between the

camera adapter and the

eyepieces is not adjusted

properly.

The aperture diaphragm of the

condenser is too wide open.

The field diaphragm is too wide

open.

Lens components of the

microscope and the cover glass

on the bottom of the camera are

dirty.

The microscope and camera are

being subjected to vibration

during acquisition.

Remedy

Focus the microscope on the sample.

Adjust the parfocality between the

camera adapter and the eyepieces

properly.

Set the aperture diaphragm to 75% of the

objective's numerical aperture and focus

the microscope on the sample.

Narrow the field aperture appropriately

and focus the microscope on the sample.

Clean the objective, condenser, window

lens of the microscope, and the cover

glass on the bottom of the camera (see

page 21).

Acquire images in an environment where

the microscope and camera are not

subjected to vibration. It is effective to use

an anti-vibration table.
