Abstract
A night vision goggle device is fabricated for consumer use. The device employs interpupillary and diopter adjustments for each eye of the user. The combined adjustment mechanism incorporates manually operable control knobs located on the housing and one knob for each of the eye pieces. Each control knob is capable of moving both in a forward and rear mode and in a transverse mode. The knob can provide diopter focus adjustment for a front to back motion and for lateral movement or transverse movement the control provides for interpupillary adjustment. The movement of the knob and the removal of pressure or force from the knob enables the optical assemblies to be locked in position by a friction fit.
