RIX Infinity Iris Diaphragm (RIID) is precision machined from different metal materials, making the products durable, reliable, and comfortable to the touch. It can be fixed to the NVG objective lens through threads and is compatible with RNV-31S and PVS-14. RIID has a smooth aperture, allowing stable adjustment of iris within the range of 1.5mm and 21mm, allowing users to see objects at all distances without refocusing the NVG objective lens and helping users to use it perfectly in different lighting environments.
