The Rigel 5700 was introduced to the US market as the result of specific requests from police departments in the Pacific Northwest, who purchased Rigel Optics Night Vision goggles for emergency preparedness.  The Rigel 5700 allows public safety organizations to wear protective Kevlar helmets beneath the Rigel Optics night vision goggles and enjoy hands-free night vision.  The Rigel 5700 helmet adapter also features a flip-up mechanism to vertically raise the goggles from the users head when not in use. 

The Rigel 5700 helmet adapter retails for $139.00, and can be used only with the Kevlar brand anti-riot helmets.

Rigel Optics is an American based company providing high-quality night vision and other optical products inclusive of night vision binoculars, goggles, scopes, and optical glasses to private individuals, companies, and public organizations in the US.
