ABSTRACT:
A thermally and mechanically stable muzzle reference system collimator asbly. The assembly comprises a muzzle reference system collimator and an adaptor plate to adapt the muzzle reference system collimator to the muzzle of a gun. The muzzle reference system collimator and adaptor plate are made up of materials having a low coefficient of thermal expansion. The adaptor plate is bonded to the gun barrel through materials which are capable of absorbing, rather than transmitting, the shock of firing to the muzzle reference system collimator and its fragile internal optical components.
