Relubrication may be required
after several years (please send
the item to Leica Service).
The achromatic Ergo objective 0.4×–0.63× can be used to
ergonomically and accurately focus in the range of 90 mm
(63.5–153.5 mm) without changing the viewing height. At the
same time, magnification and working distance can be
changed without time-consuming change of objectives.
Frequently repeated fine-motor tasks, such as focusing by
hand, can lead to muscle fatigue and hand problems. Using the
Leica motor focusing system, every equipment can be moved
up and down without applying force.
Interpupillary distance, eye contact
The interpupillary distance is correct
when you see a single circular field when
viewing with both eyes.
Look into the eyepieces and use both
hands to move the eyepiece tubes closer
together or further apart.
The distance between eye and eyepiece measures approx.
22 mm for 10×/21B wide-field eyepieces for persons wearing
glasses and 12 mm for 10×/21 wide-field eyepieces.
Slowly approach the eyepieces with
your eyes until you can see the complete
image field without corner cutting.
