The Wilcox Filter Assembly is designed for use with the AN/PVS-14/15/18 and F5050, and easily attaches to a variety of NVG devices to reduce the green backsplash of light that occurs when using night vision. Featuring an amber wavelength-controlled polycarbonate lens, this filter effectively cancels out most of the green eye splash from NVGs, providing tactical advantage to the operator. A padded rubber eye cup surrounds the lens, uniquely designed to protect the eye socket from impact injury, and further eliminate NVG light pollution from escaping the eyepiece.
