Night vision devices contain sensitive optical, electrical and image-intensifier components. Use only tools designed for the relevant retaining rings, lens assemblies and housing interfaces. Incorrect tools, excessive torque or incompatible purge fittings can damage threads, optical coatings, seals or the image intensifier tube.
