Eyepiece Assembly.
Figure 2-23.
Eyepiece Assembly.
The eyepiece assembly (Figure 2-23) contains mechanical shutters and
a diopter focus mechanism.
The shutters prevent light from passing
out of the eyeshield except during operator use.
The diopter focus
mechanism allows reticle focus adjustments.
The shutters are
attached to the inside of the collapsible eyecup.
Pressing the
collapsible eyecup into the eyeshield assembly causes the shutters to
fold away from the viewing path.
Rotating the diopter adjustment
grip moves the eyepiece lens assembly in or out of the eyepiece
housing assembly to focus the reticle.
