Abstract
A night vision binocular assembly ( ) capable of converting low light and infrared energy into a visible image. The night vision binocular assembly ( ) includes at least one objective lens assembly ( ), image intensifier tube (64), collimator lens assembly ( ) and diopter cell assembly ( ) encased in an easy to assembly waterproof housing ( ). The objective lens assembly ( ), image intensifier tube ( ), collimator lens assembly ( ) and diopter cell assembly ( ) are all supported by a common base structure ( ) within the housing ( ). As a result, variations caused by thermal expansions and contractions are evenly distributed among the various optical elements, thereby preserving a predetermined optical relationship between those elements. Simple button controls ( ) are used to operate and adjust the night vision binocular assembly ( ). The button controls ( ) are disposed on a common circuit board ( ). An elastomeric structure ( ) is disposed between the circuit board ( ) and the interior of the binocular housing ( ). The circuit board ( ) is affixed to the interior of the binocular housing ( ) in a manner that compresses the elastomeric structure ( ) against the binocular housing ( ) to provide a water tight seal. The elastomeric structure ( ) has switch membranes or domed portions which extend through apertures ( ) in the housing ( ) creating both a fluid impermeable seal with the housing ( ) and a means for the tactile engagement of the switches on the below lying circuit board ( ).
