The Pixfra Sirius S650D Dual-View Thermal Monocular is the standout model in the Sirius range, and the only one to offer dual-view capability. With a simple twist, you can switch between a 25mm wide field-of-view lens for scanning large areas and a 50mm lens for more detailed observation at distance, effectively giving you two monoculars in one. This makes it a highly versatile choice for wildlife observation, conservation work, and any situation where both wide-area searching and closer thermal inspection matter.
At the heart of the S650D is a 640×512, 12µm thermal sensor with an impressive ≤18mK NETD sensitivity, delivering excellent thermal detail even in challenging conditions. Paired with its 25mm f0.88 / 50mm f1.1 dual objective lens system, it offers sharp, high-contrast thermal imagery and a detection range of up to 2600m. A 50Hz refresh rate keeps the image smooth and responsive, while magnification of 1.72x on the 25mm lens and 3.45x on the 50mm lens, plus 1x, 2x, 4x and 8x digital zoom, gives you the flexibility to adapt to changing observation needs.
Viewing comfort is equally impressive thanks to the 0.49-inch 1920×1080 OLED display, which produces a crisp, vivid image while helping to reduce eye strain during longer sessions. Pixfra’s AI-powered image calibration continuously learns from captured images to optimise picture quality over time, while useful digital features such as video recording, snapshot capture, hot spot tracking, Wi-Fi hotspot connectivity and 64GB of built-in storage add even more functionality in the field.
The Sirius S650D also reflects Pixfra’s strong focus on design and usability. Its streamlined three-button control layout supports comfortable one-handed operation, while details such as the integrated illuminated logo power button, carbon fibre styling accents and embossed focus wheel give it a premium feel. A metal lens cover adds extra protection against dust, scratches and knocks, and the robust IP67-rated housing ensures dependable performance in harsh weather and demanding environments.
Powered by a replaceable 18650 battery, the S650D provides up to 6 hours of runtime, with a quick-release battery system that makes swapping batteries fast and simple when you need longer sessions in the field. Compact for its capability at 537g, and built to operate in temperatures from -30°C to +55°C, the Sirius S650D is a highly capable thermal monocular that combines advanced imaging performance, practical digital features and genuine dual-lens flexibility in one refined package.
