Universal boresight tool for small arms weapons

摘要

Boresighting apparatus that includes a multispectral reflective collimator combined with an adjustable rhomboid reflector that allows boresighting of any wavelength sighting, pointing, aiming or rangefinding device disposed on a small arms weapon. The boresighting apparatus comprises a housing and a small arms weapon adapter for securing the housing to small arms weapons having different calibers. An illuminated or heated target is disposed in the housing for selectively providing an image of an illuminated or heated target pattern. A power source is coupled to the target for providing power to selectively illuminate or heat the target. An adjustment mechanism is provided for incrementally adjusting the optical location of the target and thus the location of the target pattern. A mirror, such as an off-axis parabolic mirror, is disposed to reflect the image of the illuminated or heated target pattern along a visual optical path. A beamsplitter is disposed along the visual optical path for transmitting visible and infrared radiation, and for reflecting laser radiation derived from a laser rangefinder disposed along a laser optical path toward the target. A laser radiation filter is disposed along the visual optical path for preventing transmission of laser radiation to the eye of a user. A folding mirror is disposed along the laser optical path for reflecting the laser radiation derived from the laser rangefinder to the beamsplitter to superimpose the laser radiation on the target pattern.
