Features:

Gyroscopic Image Stabilization with ±5° Motion Correction

At the heart of the Fujinon Stabiscope Binoculars is a sophisticated mechanical gyroscope that actively stabilizes the image by counteracting vibrations and motion up to ±5° on both vertical and horizontal axes. This is not just a digital or passive stabilization—it's a full-scale mechanical solution using a high-speed internal flywheel. Whether you're scanning the horizon from a turbulent helicopter, tracking targets from a bouncing boat, or observing from a moving vehicle, the Stabiscope delivers unwavering, stable visuals with professional-grade reliability. This core feature sets the binoculars apart from conventional models, especially in mission-critical scenarios where precision and clarity are non-negotiable.

Dual Magnification Models for Varied Operational Needs (12x40 & 16x40)

Fujinon offers two purpose-built models—S1240 and S1640—to accommodate different field requirements. The S1240 delivers 12x magnification and a wide 82-meter field of view at 1,000 meters, ideal for mid- to long-range observation with increased situational awareness. On the other hand, the S1640 offers a powerful 16x magnification with a tighter 59.4-meter field of view, giving users the optical reach needed for pinpoint surveillance at extended distances. Both use a 40mm objective lens for excellent light intake, making either model versatile for daylight and low-light environments.

Exceptional Optical Quality with Fujinon EBC Multi-Coatings

Each optical surface within the Stabiscope binoculars is treated with Fujinon’s proprietary Electron Beam Coating (EBC), which significantly enhances light transmission while minimizing glare and chromatic aberration. This results in crisp, high-contrast images with accurate color rendition, even in challenging lighting such as dusk, dawn, or overcast conditions. The phase-coated BAK4 roof prisms further sharpen edge clarity and ensure superior optical resolution throughout the entire field of view. These features make the Stabiscope a trusted tool for applications where high-definition visual accuracy is essential.

Three-Way Power Supply for Maximum Field Versatility

Unlike typical binoculars that rely on a single battery type, the Fujinon Stabiscope supports three power options—4 AA batteries, a 2CR5 lithium battery, or a 12–32 VDC external power source. This triple-power versatility allows users to adapt on the fly, whether they’re on a prolonged mission, in remote areas with limited access to replacement batteries, or connected to vehicle or aircraft power systems. The inclusion of a DC regulator and external power input enhances reliability and ensures operational continuity even in extended deployments.

Fully Waterproof and Fog-Proof for Harsh Environments

Designed for rugged, all-weather performance, the Fujinon Stabiscope is waterproof, nitrogen-purged, and sealed with high-grade O-rings to eliminate internal fogging and moisture ingress. Whether you're facing ocean spray, heavy rain, high humidity, or freezing temperatures, these binoculars are built to perform. Rated for operation in extreme climates ranging from -20°C to +50°C, they can be trusted in both arctic and tropical conditions without compromise. This robust environmental sealing adds a layer of operational security that professionals in maritime, aviation, and tactical fields demand.

Ergonomic, Ambidextrous, and One-Handed Operation

The body of the Stabiscope is engineered for comfort and adaptability. With a symmetrical, ambidextrous design, users can comfortably hold and operate the device with either hand—even upside down, a rare feature in the binocular world. The shape, control placement, and weight balance allow for secure one-handed operation, even while wearing gloves or managing other equipment. This ergonomic attention to detail makes the binoculars well-suited for high-mobility use in helicopters, boats, or on foot.

Interchangeable Eyepieces with Optional Day/Night Capability

One standout feature of the S1240 D/N variant is its ability to integrate interchangeable eyepieces, enabling seamless transition between standard daytime optics and night vision technology. This makes the binoculars viable for continuous, 24-hour operations where visibility fluctuates. For users requiring surveillance, rescue missions, or tactical monitoring through the night, this add-on provides essential flexibility. The swappable configuration also extends the utility and lifespan of the equipment by allowing tailored customization.

Extended Eye Relief for Comfortable Viewing with Eyeglasses

With 17 mm of eye relief in the S1240 and 12 mm in the S1640, the Stabiscope binoculars are designed to be eyeglass-friendly.
