The TXZJ ELF-FB20 is a thermal-integrated dual-tube night vision binocular that combines Gen 2+ NNVT image intensifier tubes with thermal imaging technology in a single system.
Designed for advanced nighttime observation, the ELF-FB20 combines traditional image intensification with thermal detection capabilities, providing users with additional visual information in challenging low-light environments.
The dual-tube configuration provides binocular viewing and improved depth perception, while the integrated thermal system adds the ability to detect heat signatures.
Available with White Phosphor (WP) or Green Phosphor (GP) NNVT tubes, the ELF-FB20 offers three selectable FOM configurations to accommodate different performance requirements.
1600–1800 FOM
1800–2000 FOM
2000–2500 FOM
All three configurations feature Gen 2+ NNVT image intensifier tubes, with the selected FOM range determining the specified tube performance category.
Integrated Thermal Imaging: Combines thermal detection with conventional image-intensified night vision.
Dual-Tube Binocular Design: Provides binocular observation with improved depth perception.
Gen 2+ NNVT Intensifier Tubes: Available in three FOM performance ranges.
White or Green Phosphor: Choose the preferred image intensifier display colour.
Combined Observation Capabilities: Thermal imaging and image intensification provide complementary information during nighttime use.

FOM (Figure of Merit) is calculated by multiplying an image intensifier tube's resolution by its signal-to-noise ratio (SNR). Higher FOM values generally indicate greater overall tube performance, although actual image quality also depends on environmental conditions and individual tube characteristics.
Note: Individual image intensifier specifications may vary within the selected FOM range.
