1. An electronic focal adjustment system for a night vision device, the electronic focal adjustment system comprising:
a focal adjustment apparatus that couples to an objective lens of the night vision device, the focal adjustment apparatus comprising a housing that has one or more first ports, a lens ring, a lens mount, one or more gears, and a motor that interacts with the one or more gears, the one or more gears rotate the lens ring, the lens mount, and the objective lens of the night vision device;
a power source apparatus that couples to and communicates with the focal adjustment apparatus; and
a button apparatus that communicates with the power source apparatus to adjust the objective lens of the night vision device.
 
13. An electronic focal adjustment system for a night vision device, the electronic focal adjustment system comprising:
a focal adjustment apparatus that couples to an objective lens of the night vision device, the focal adjustment apparatus comprising:
a housing with a backplate and a cover,
one or more first ports,
a lens ring,
a lens mount,
a motor that interacts with one or more gears, the one or more gears rotate the lens ring and the lens mount to adjust the objective lens;
a power source apparatus that provides power to the electronic focal adjustment system, the power source apparatus comprising a switch to actuate the power source apparatus and a processor;
a button apparatus with one or more buttons;
a sensor device comprising one or more sensors and a gyroscope;
wherein the button apparatus, the sensor device, and the focal adjustment apparatus communicate with the power source apparatus to adjust the objective lens of the night vision device to pre-calibrated focal points.
 
18. An electronic focal adjustment system for a night vision device, the electronic focal adjustment system comprising:
a focal adjustment apparatus that couples to an objective lens of the night vision device, the focal adjustment apparatus comprising:
one or more first ports,
a lens ring comprising finger grooves,
a lens mount,
a housing ring that mates with the lens mount, the lens ring, and the objective lens of the night vision device;
a motor that interacts with one or more gears, the one or more gears rotate the lens ring, the lens mount, and the objective lens of the night vision device;
a power source apparatus that provides power to the electronic focal adjustment system, the power source apparatus comprising a switch to actuate the power source apparatus and a processor;
a button apparatus with one or more buttons and an adjustment wheel;
a sensor device comprising a sensor housing and sensor back plate, the sensor housing comprising:
one or more sensors,
a plurality of sensor ports that receive cables, and
a gyroscope;
a lens cover comprising a plurality of fingers that fasten to the finger grooves of the lens ring;
wherein the button apparatus, the sensor device, and the focal adjustment apparatus communicate with the power source apparatus to adjust the objective lens of the night vision device to pre-calibrated focal points.
