Leica DM IRB manual Inserting the eyepieces, Inserting graticules, Screw the retainer ring back

Screw the reflection optics (46.3) to the tube flange with the coupling ring (46.2). Align the macro adapter (46.5) to the macro dual zoom and secure with the screw ring (46.6). Screw the macro adapter and macro dual zoom to the reflection optics with the coupling ring.

Check that the guide pin engages in the groove.

Inserting the eyepieces

The eyepieces are inserted into the eyepiece tubes.

Use the following eyepieces only:

HC PLAN 10x/20

HC PLAN 10x/20 M

HC PLAN 10x/22

HC PLAN 10x/22 M

HC PLAN 12.5x/16 M

Widefield 16x/14 B (M)

Widefield 25x/9.5 B (M)

(a spacer ring is required for the widefield objectives)

Information on the diameter, the visible area of the specimen and the total magnification of the microscope can be found in the chapter “Technical data; performance data”.

Inserting graticules*

You can retrofit graticules yourself to the HC PLAN eyepieces in the above list.

Graticules can only be inserted in eyepieces with an adjustable eyelens = M type. The sec- ond eyepiece should be an M type as well.

!Important!

Be very careful to keep the optical surfaces clean. Any dust particles and finger marks will show up in the image.

The graticule diameter for all HC PLAN eye- pieces is 26 mm.

Eyepieces 10x/20 M and 12.5/16 M only:

●Screw the retaining sleeve out of the under- neath of the eyepiece.

●Insert the graticule with the coated side facing downwards (towards the objective). If there is any lettering on the graticule it must be imaged the right way round when viewed in the later observation direction.

●Screw the retaining sleeve back in.

Eyepieces 10x/22 M only:

●Screw out the underneath of the eyepiece.

●Remove the retainer ring inside it with a blunt blade.

●Insert the graticule with the coated side facing downwards (towards the objective). If there is any lettering on the graticule it must be imaged the right way round when viewed in the later observation direction.

●Screw the retainer ring back in.
