2.1 Bright-field Microscopy
Bright-field microscopy is the most basic observation method using diascopic illumination.
For details on the configuration and the assembly of the microscope for bright-field microscopy, see “4.2.1
Basic Configuration (For Bright-field Microscopy).”
1 Install the microscope.
(1) Carry the microscope from the storage location
and place it at your location.
(2) Fix the direction of the eyepiece tube to the
observation point (the binoculars are toward
you).
Loosen the fixing screw for the eyepiece tube a
