Spectacle Model

Optical Section Vertical Adjustment

• Loosen screw that attaches
optical section spectacles.
• Reposition optical section to insure
proper alignment with user's eyes.
• Tighten screw to maintain
optical section location.

Adjusting for User Refractive Error

(Spectacle Models Only)
The optimal working distance from the object is 15" (38.1cm) - 17" (43.2cm). If this
model is used without corrective lenses and user is myopic or hyperopic, then the
user will need to work closer or farther from object, depending on refractive error.
To compensate for this, the spectacle models can be fitted with corrective lenses
by an eyecare practitioner of your choice. Please bring the following information
to assist your eyecare practitioner in fitting your prescription lenses.

Setting the Interpupillary Distance

The Interpupillary Distance (IPD) Controls move the oculars and are located on the
bottom of the optical section. These oculars move independently of one another.
• To set IPD properly, observe an object at approximately15 inches (38cm).
• Close the left eye and adjust the IPD control under the right eye until the
viewed image is centered.
• Now close the right eye, keeping the left eye open, and adjust the IPD control
for the left eye until that image is centered.
• Open both eyes and the object should be clear and centered.
