Professional Night Vision Maintenance, Repair, and System Upgrades
At Quad Defense, we provide professional Night Vision servicing, repair, and housing upgrades for a wide range of night vision devices including PVS-14, RNVGA, Katana, DTNVS, GPNVG, and other modern systems.
Night vision devices are precision optical instruments that require proper maintenance to ensure peak performance. Over time, use, environmental exposure, and internal seal degradation can affect clarity, alignment, and reliability.
Our Night Vision experts specialize in restoring, maintaining, and upgrading night vision systems so they remain mission ready and operating at their highest capability.
Professional Night Vision Device Servicing
Routine servicing ensures your night vision device maintains proper performance, optical alignment, and internal environmental protection.
Every device sent to Quad Defense undergoes a full inspection and diagnostic evaluation by experienced technicians using professional equipment and calibrated optical tools.
Our servicing process helps prevent fogging, maintain tube alignment, and identify potential issues before they become major failures.
Night Vision Service Includes
• Complete device inspection and function test
• Precision collimation and optical alignment
• Nitrogen purge to remove moisture and prevent internal fogging
• Internal and external device cleaning
• Housing seal inspection
• Electrical and gain control testing (if applicable)
• Minor repairs and adjustments
• Final performance verification
Whether your system is used for professional duty, training, or recreational night operations, routine maintenance extends the life of your device and ensures dependable performance when you need it most.
Night Vision Housing Upgrades
If your image intensifier tubes are still strong but your housing is outdated, upgrading the housing is often the most cost-effective way to modernize your night vision system.
Quad Defense specializes in transferring existing tubes into modern housings with improved durability, lighter weight, and advanced features.
Popular upgrade paths include moving legacy systems into housings that offer:
• Reduced weight and improved ergonomics
• Articulating pod designs
• Manual gain control
• Improved durability
• Compatibility with modern helmet mounts and accessories
