PRE ORDER - ETA November 2026

The IR Monster ELF-FB 20 Enhanced Night Vision Binoculars combine image-intensified night vision with thermal imaging in a compact dual-band fusion platform. Designed to enhance nighttime observation and detection, the ELF-FB 20 combines traditional low-light image intensification with a 640×512 thermal detector, allowing thermal information to be integrated into the night vision image.

The ELF-FB 20 features a 640×512, 12μm thermal detector, 1× magnification, a 27mm focal length and a 40° night vision field of view. Highlight and Outline fusion modes provide different methods of displaying thermal information, helping the user distinguish heat signatures while retaining the environmental detail provided by image-intensified night vision.

Designed with improved image intensifier compatibility and a miniaturised, lightweight architecture, the ELF-FB 20 supports both 10160 and 11769 image intensifier tubes. A 1280×1024 OLED display supports the thermal imaging system, while the complete unit weighs approximately 530g. The system also supports wireless connectivity with the IR Searcher mobile application for accessing images, videos and compatible remote functions.

Dual-Band Night Vision & Thermal Fusion

The ELF-FB 20 combines two complementary imaging technologies within a single binocular night vision platform. Image intensifier tubes provide the familiar low-light environmental detail of conventional night vision, while the integrated thermal detector provides additional information based on differences in thermal energy.

By combining these two imaging channels, the ELF-FB 20 is designed to improve nighttime observation and recognition compared with relying on a single imaging technology alone.

640×512 Thermal Imaging

• Thermal detector resolution: 640 × 512
• Pixel pitch: 12μm
• Integrated thermal and night vision fusion architecture
• Highlight fusion display mode
• Outline fusion display mode

The integrated 640×512 thermal detector provides the thermal imaging channel used by the ELF-FB 20 fusion system. Thermal information can be presented using Highlight or Outline modes depending on the required viewing configuration.

Highlight & Outline Fusion Modes

The ELF-FB 20 provides two thermal fusion image modes designed to integrate thermal information with the image-intensified night vision view.

• Highlight Mode: emphasises detected thermal information within the night vision image.
• Outline Mode: displays thermal information around the outline of detected objects while preserving surrounding night vision detail.

Image Intensifier Tube Compatibility

The IR Monster ELF-FB 20 is designed to support 10160 and 11769 image intensifier tube formats. This provides flexibility when configuring the binocular system around compatible image intensifier technology.

Image quality and low-light performance depend significantly on the specific image intensifier tubes installed in the device. Tube specifications should therefore be considered separately from the thermal detector specification when selecting a complete ELF-FB 20 configuration.

Night Vision Optical Performance

• Magnification: 1×
• Night vision field of view: 40°
• Focal length: 27mm
• Image intensifier compatibility: 10160 / 11769

With 1× magnification and a 40° night vision field of view, the ELF-FB 20 retains the familiar viewing format associated with conventional head-mounted night vision binoculars while adding an integrated thermal imaging channel.

1280×1024 OLED Display

The thermal imaging system uses a 1280×1024 OLED display. The display forms part of the electronic thermal and fusion imaging architecture while the image intensifier channels provide the conventional night vision image.

Compact & Lightweight Fusion NVG Design

IR Monster developed the ELF-FB 20 with an emphasis on miniaturisation and reduced weight compared with its previous-generation enhanced night vision system. The complete device is specified at approximately 530g.

For helmet-mounted use, total system weight should also take into account the helmet, mount, power configuration and other accessories used with the binoculars.

IR Searcher Mobile App Connectivity

The ELF-FB 20 supports wireless connectivity with the IR Searcher mobile application. According to IR Monster, the application can receive images and videos from compatible devices and provides remote device control and file-sharing functionality.

Ideal Applications

• Nighttime observation
• Outdoor search and rescue
• Wildlife and animal observation
• Low-light navigation
• Professional night vision applications
• Situational awareness in low-light environments

Why Choose the IR Monster ELF-FB 20?

The ELF-FB 20 Enhanced Night Vision Binoculars provide an alternative to conventional night vision binoculars by integrating a dedicated 640×512 thermal detector directly into an image-intensified binocular platform. The combination of 1× night vision optics, a 40° field of view, 10160 and 11769 tube compatibility and selectable thermal fusion modes provides both traditional night vision detail and additional thermal information within one head-mounted system.
