The Onyx filter installs onto any milspec PVS-14 eyepiece and instantly provides the user with a softened black and white image which reduces eye strain for long term use, and helps minimize image noise.
These filters are very useful for users using a night vision and thermal monoculars simultaneously, as the black and white image will match the achromatic output of most thermal devices and provide a more seamless experience.
Each filter sold individually. For a set of binos, order two.
