Fortuna 3B Thermal Imaging Binocular

• Two-eye thermal viewing: The binocular layout reduces eye strain during long observation sessions and makes tracking moving heat sources more natural than with a single-eyepiece device.
• 384x288 thermal sensor with 17.00 μm pixel pitch: This sensor format gives the Fortuna 3B enough detail for reliable detection and target observation while keeping the unit compact and light for field carry.
• AMOLED display: An AMOLED screen delivers clear contrast and stable viewing in darkness, helping the user read thermal detail comfortably in changing outdoor conditions.
• 2500.00 m detection range: Long detection capability helps spot heat signatures early, which is valuable for scanning open ground, woodland edges, and large areas in poor visibility.
• Compact 400.00 g housing: Low weight and small overall dimensions make the binocular easier to carry on patrol, on a hunt, or as part of a helmet-mounted observation setup.

About the Fortuna Googles Series

The Fortuna Googles series is built as a family of thermal binoculars for observation and tracking in darkness and difficult weather, with an emphasis on hands-free use and practical field adaptability. Within the range, Fortuna uses a bayonet lens mount that allows the body to work with interchangeable lenses, giving the platform broader application than a fixed-format thermal viewer. The series is also designed for two-eye observation, which improves comfort during extended scanning and makes it better suited to surveillance, hunting, and mobile field use.

Another defining trait of the series is its modular approach. Fortuna lists compatibility with an external power bank, video output, and an optional Fortuna laser rangefinder module that can display distance information in the device. The platform also supports use with tactical helmets and head mounts, which points to a design intended not only for handheld observation but also for more integrated setups. In practice, the series is aimed at users who need a thermal binocular that can be configured around mission length, viewing distance, and mounting preference rather than limited to one fixed role.

About the Fortuna 3B Thermal Imaging Binocular

The Fortuna 3B Thermal Imaging Binocular is a compact thermal observation device built around 1.00 x magnification, which makes it especially useful for close to medium-distance scanning where situational awareness matters more than narrow-field target study. This kind of base magnification helps the user move through terrain, monitor wider sectors, and maintain a more natural sense of scale while observing heat sources. With a stated 2500.00 m detection range, the unit is suited to early spotting tasks in darkness, fog, or other low-visibility conditions where conventional optics lose effectiveness.

Its 384x288 sensor, 17.00 μm pixel pitch, and 50.00 Hz refresh rate support smooth thermal viewing and stable image presentation when following moving animals, vehicles, or people. The AMOLED display complements this by providing clear contrast for prolonged night use. A NETD of 60.00 mK and automatic calibration help maintain usable thermal separation without adding unnecessary handling complexity in the field. The binocular also records images and video and provides video output, which is useful for documentation, review, or external display integration.

Physically, the 3B remains easy to carry at 400.00 g and measures 155.00 mm in length, making it practical as a mobile observation tool. Nitrogen filling, waterproof and fogproof construction, and an operating range of - 30° / + 50° C support use across demanding weather conditions. The -5 / +5 Dpt diopter range further helps adapt the binocular to different users without slowing deployment.

About Fortuna

FORTUNA is a Russian manufacturer of thermal imaging devices focused on hunting, night shooting, and sport shooting applications. The FORTUNA trademark was registered in 2010, and the company’s thermal imagers are produced at LLC Modul in Moscow, Russia. Alongside hardware development, the company also develops software for its products, which reflects a vertically focused approach to thermal imaging systems rather than simple assembly.

The brand’s product range includes thermal sights, monoculars, binoculars, and clip-on attachments, covering both observation and weapon-mounted use. Across these categories, Fortuna is known for building dedicated thermal devices for field use in low-light and no-light conditions. Its experience in thermal optics is directly relevant to products such as the Fortuna 3B, where compact design, thermal detection capability, and practical outdoor usability are more important than conventional daytime optical performance.
