Thermal Scopes
The PIXFRA Sirius series is a range of handheld thermal monoculars designed for outdoor observation and wildlife spotting. Choose from a compact 384 × 288 sensor model or 640 × 512 models, with fixed or dual-field optics. All models listed below use 12 μm pixels and offer manufacturer-rated thermal sensitivity of ≤18 mK.
384 × 288 sensor, 35 mm F1.0 lens, 3.68× optical magnification and stated detection distance up to 1,800 m.
640 × 512 sensor, 35 mm F1.0 lens, 2.41× optical magnification and stated detection distance up to 1,800 m. A wider field of view makes it useful for scanning.
640 × 512 sensor, 50 mm F0.9 lens, 3.45× optical magnification and stated detection distance up to 2,600 m.
640 × 512 sensor with dual 25 mm and 50 mm optical fields. Switch between a wider view for searching and a narrower view for longer-range observation; stated detection distances are up to 1,300 m and 2,600 m respectively.
640 × 512 sensor, 50 mm F0.9 lens and integrated laser rangefinder. Stated detection distance up to 2,600 m.
Models include a 0.49-inch 1920 × 1080 OLED display, 50 Hz imaging, digital zoom, six colour palettes, hot-spot tracking, photo and video recording, Wi-Fi, built-in 64 GB storage, USB Type-C, replaceable 18650 battery and IP67 protection. Manufacturer-listed battery life is approximately 6 hours for the 640 × 512 models and up to 7.5 hours for the S435, with Wi-Fi off under stated test conditions.
Detection distances are manufacturer estimates and depend on target size, weather, terrain and viewing conditions. Detection is not the same as recognition or identification.
