Precautions
The loupe optics should be worn as close as possible to your eyes to achieve the
greatest field of view and declination angle. When adjusting, the loupe barrels should be
against or close to the eye shield with the loupes between a 45˚ and 60˚ angle.
Incorrect loupe position decreases field of view and declination angle.

Step-by-Step Directions
1. Focusing
1.0 Loupe optics have a preset focal distance. An easy way to determine the working
distance of the loupe optics is to view your thumbs while moving them in and out of focus.

2. Adjusting Interpupillary Distance (IPD)
2.0 The only adjustment that is usually needed is to set the interpupillary distance (IPD).
While focusing on an object, pull up on the Interpupillary Adjustment Knob and rotate,
moving the optics apart and together. Look at the outside rings of the field of view when
adjusting the IPD.
2.1 Focus on an object with the optics far apart.
2.2 Bring the optics together until a single circle is observed. When a single circle is
observed, the IPD is set.
