ELF-31H

F1.2 Enhanced Dual Tube System with Improved Optical Performance

The ELF-31H is an upgraded evolution of the well-known J31 platform, designed to deliver improved brightness and clarity while maintaining a cost-effective dual tube night vision binocular configuration. Featuring an advanced 27mm F1.2 objective lens, the ELF-31H captures more ambient light, resulting in a brighter and sharper image in low-light conditions.

An anti-reflective optical coating helps reduce glare and enhances contrast, improving visibility in challenging environments. This upgraded optical system makes it easier to detect details, improving performance for professional and enthusiast night vision users.

The ELF-31H maintains the compact and practical design that made the J31 popular while offering improved optical efficiency and enhanced viewing performance for demanding applications.
