Abstract
A night vision system has an image intensifier tube that may be installed or replaced without requiring realignment of the optics. A first locating feature may be coupled to the image intensifier tube to align the first locating feature with an input optical axis of the image intensifier tube. A second locating feature may be coupled to the image intensifier tube to align the second locating feature with the output optical center of the image intensifier tube and form an image at a predetermined location along the output optical axis.
Claims16
A night vision system, comprising:
- an image intensifier tube;
- a first locating feature coupled to a distal end of the image intensifier tube,
- a second locating feature coupled to a proximal end of the image intensifier tube,
- the first locating feature configured to interact with a third locating feature to place an input optical axis of the image intensifier tube in alignment with a first optical component;
- and
- the second locating feature coupled to the proximal end of the image intensifier tube to place a feature of the second locating feature at a predetermined distance from a focal plane of the image intensifier tube, the second locating feature configured to interact with a fourth locating feature to place an output optical axis of the image intensifier tube in alignment with a second optical component.
