The Nocturn Lightweight Diopter Housing is a precision-engineered upgrade for PVS-14 format night vision systems. Designed to reduce weight and improve balance for helmet-mounted setups, it replaces the standard Mil-Spec diopter assembly while maintaining rugged performance and long-term reliability.
This lightweight diopter housing is CNC machined and threads directly into compatible eyepieces using either a standard PVS-14 eyepiece lock ring or a diopter set screw. It is sold individually as one housing and does not include glass optics, allowing builders to pair it with the eyepiece of their choice. Whether you are designing a streamlined night vision system or optimizing a dual-tube setup to reduce neck fatigue, this is a proven performance upgrade trusted by professional users and enthusiasts.
Compatible with both traditional Mil-Spec eyepieces and lightweight Rochester Precision Optics (RPO) eyepieces, the Nocturn Lightweight Diopter Housing is ideal for users who want to drop weight without compromising mechanical precision. Builders who want to further lighten their setup can pair this with an ultralight objective and lightweight accessories to create a purpose-built configuration for extended use.
For complete builds or installation support, our team at Nightfall Optics is available to help match this diopter housing with compatible eyepiece options or PVS-14 components.
