Applications
The eyepiece is designed for the PVS-14 monocular. It is suitable for replacing a damaged eyepiece, assembling a night vision device from an SKD housing, and reducing the weight of a helmet-mounted device. Replacing the optical assembly requires disassembling the device and readjusting the focus, so we recommend that it be performed by a service center or someone with experience assembling night vision devices.
