The InfiRay FB-20 is an advanced thermal-integrated dual-tube night vision binocular, combining Gen 3 NNVT image intensifier tubes with thermal imaging technology in a single system.
Designed for demanding low-light environments, the FB-20 combines conventional image intensification with thermal detection capabilities, providing enhanced situational awareness and additional visual information during nighttime observation.
Its dual-tube binocular configuration provides natural stereoscopic viewing and improved depth perception, while the integrated thermal system enables the detection of heat signatures that may be difficult to distinguish through conventional night vision alone.
The FB-20 is available with White Phosphor (WP) or Green Phosphor (GP) Gen 3 NNVT tubes, three selectable FOM performance ranges, and two housing colour options: Black and Tan.
Choose from three FOM configurations based on your performance requirements:
1600–1800 FOM — Gen 3 NNVT image intensifier tubes.
1800–2000 FOM — Higher-FOM Gen 3 NNVT image intensifier tubes.
2000–2500 FOM — High-specification Gen 3 NNVT image intensifier tubes.
All configurations feature Gen 3 NNVT technology, with individual tube specifications varying according to the selected FOM range.

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 image intensifier performance, although actual image quality also depends on lighting conditions and individual tube characteristics.
Note: Individual image intensifier specifications may vary within the selected FOM range. Final configuration is determined by the selected tube performance, phosphor type, and housing colour.
