1. An aiming system comprising:
a beam source assembly having a mounting plate and a beam source for generating an input beam from an exit surface, the exit surface defining a central axis along which the input beam is to propagate;
a collimator assembly having a body defining an outer surface and an inner surface parallel thereto, the collimator assembly having a lens group disposed between the outer surface and the inner surface, wherein the lens group defines a tilt axis forming an acute angle to the parallel outer and inner surfaces and wherein the tilt axis has a tilt angle, α, relative to the central axis, the lens group positioned to deflect the input beam from the central axis onto the tilt axis,
the collimator assembly further having a recess positioned above the lens group and having an optical element sealably mounted within the recess to convert the input beam into an aiming pattern at a focal distance of the lens group; and
a chassis defining an outer cavity within which the collimator assembly is mounted and an inner cavity within which beam source is mounted.
