Night Vision 3x Afocal Lens Attachment Adapter (37mm clamp to M30.3x0.8)

Front side - M30.3x0.8 (1.2″-32tpi) thread

Rear side - 37mm inner tube

This adapter replaces the military style snap on lens connector that attaches the 3x afocal lens to the front of the PVS-7, PVS-14, or ENVIS lens equipped night vision device. The longer length allows the user to mount a standard 1.25″ astronomy filter to the front of the device objective, and then the 3x lens can be mounted over the filter (the RafCamera 1.25″ astro filter (M28.5x.06) to 1.2″-32tpi adatper is required to mount the filter to the device objective).

Alternately, two of these can be used with the filter adapter screwed into the front and the filters mounted on the 3x afocal adapter so that filters can be changed without threading and treadling the filters.
