The PVS-7 Collimator PVS-7B/D is an essential optical component of the PVS-7 night vision goggle system, designed to ensure proper alignment and calibration of the device’s internal optics. This specialized collimator helps to project a precise reticle or point of focus, allowing the user to achieve accurate targeting and enhanced clarity during low-light or nighttime operations. The collimator’s function is critical for maintaining the optical performance of the PVS-7, ensuring that the night vision goggles deliver clear, crisp images for optimal situational awareness.
