Chapter 2 Microscopy

2.2 Dark-field Microscopy under the Episcopic Illumination

Attach the items required for the dark-field microscopy under the episcopic illumination

to the microscope. (See Table 2.1.)

Focus on the sample with the bright-field microscopy under the episcopic illumination.

(See Pages 16 and 17.)

Set the microscope for the dark-field microscopy under the episcopic illumination.

1 Turn the revolving nosepiece to place the

objective of a desired magnification into the optical

path. (See 3.9.2.)

2 Pull out the BD field changeover lever to select the

“DF (dark-field)” position. (See 3.3.)

The aperture diaphragm and the field diaphragm

are fully opened. (The dial positions do not

change.)

When the polarizer/analyzer or the fl filter is

placed into the optical path, it is automatically

excluded.

3 Turn the brightness control dial to adjust the

brightness of the episcopic illumination. (See

3.2.1.)

4 Adjust the brightness with the desired ND filter in

the filter turret. (See 3.10.)

Return to the bright-field microscopy under the episcopic illumination.

1 Push in the BD field changeover lever to select the

“BF (bright-field)” position. (See 3.3.)

The aperture diaphragm and the field diaphragm

automatically return to the previous positions.

(The dial positions do not change.)

2 Turn the brightness control dial to adjust the

brightness of the episcopic illumination. (See

3.2.1)

3 Adjust the brightness with the desired ND filter in

the filter turret. (See 3.10.)
