Leica DM IRB manual Only when one eyepiece is without an adjustable eyelens

Binocular tube HCI B22 or HCI BV22

For eyepieces with inserted graticule only*:

●Greatly defocus the specimen or remove from the light path.

●Exactly focus the graticule by adjusting the eyelens with a relaxed eye (the eye relaxes best if you look out the window at a distant object for a moment).

●Focus the specimen, only adjusting the eyepiece with graticule.

●Then close this eye and focus the specimen by adjusting the second eyepiece only.

Only if neither eyepiece has a graticule inserted:

●Greatly defocus the specimen or remove it from the light path.

●Adjust the eyelens until the edge of the field of view appears sharp. When you adjust the eyelens a white line becomes visible round the basic part of the eyepiece. This indicates the correct position of the eyelens for viewers with normal or corrected eyesight.

Eyeglasses with multirange lenses (bifocal and progressive) must be removed for microscopy.

●Focus the specimen through the eyepieces.

Only when one eyepiece is without an adjustable eyelens:

●Exactly focus the specimen through this eye- piece first (close your other eye).

●Then focus the image by adjusting the eye- lens of the second eyepiece.
