ABSTRACT:
A coupling device and associated method for coupling an unassociated afocal optical assembly to a night vision apparatus in order to alter the optical power normally associated with the night vision. The coupling device includes two separate adapter rings that threadably connect to each other. The first adaptor ring is sized and shaped to threadably engage the night vision apparatus proximate the objective lens of the night vision apparatus. The second adaptor ring is sized and shaped to screw onto the output end of the afocal optical assembly. Accordingly, when the first adaptor ring is joined to the second adaptor ring, the output end of the afocal optical assembly is optically aligned with the objective lens of the night vision apparatus. Consequently, the afocal optical assembly enhances the optical power associated with the night vision apparatus.
