The IRAY QUEST-S50R RF thermal binocular is a high-resolution thermal imaging system built for hunters and field operators who need both eyes on the target during extended observation sessions. This dual-eyepiece thermal binocular pairs a 1280×1024 thermal sensor with a 50 mm f/1.1 germanium objective lens, delivering the kind of image clarity and detection range that separates serious thermal work from entry-level gear. The 2X native magnification with 16X digital zoom lets you scan large areas methodically, then dial in distant targets for positive identification—all without the single-eye fatigue that comes with handheld monoculars.
Dual AMOLED displays (1920×1200 resolution each) send a full-resolution image to both eyepieces simultaneously, creating a natural, immersive viewing experience that works the way your brain expects binoculars to work. An integrated laser rangefinder gives you real-time distance to target out to 1000 yards, while Reality+ image processing sharpens contrast and detail across the full thermal spectrum. The independent diopter adjustment on each eyepiece means you can dial in a sharp image tailored to your vision—critical for all-night sits or high-stress identification scenarios. The 15 mK NETD (noise equivalent temperature difference) keeps thermal signatures clean and readable even at maximum detection range (2850 yards), and the binocular form factor provides inherent stability during those crucial moments when you need steady glass.
Built for hunters who spend hours glassing open country or waiting in ambush, the QUEST-S50R includes an adjustable binocular harness designed to distribute weight evenly and keep your hands free for fieldwork. The internal USB-C rechargeable battery can be supplemented with standard 18650-style batteries, so you're never left dark in the field. Color palettes include standard thermal modes (White Hot, Black Hot, Red Hot) plus advanced options (Color, Violet, Crimson, Viridian) to match your hunting conditions and personal preference.

Binocular thermal imaging lets you glass with both eyes and both hands, just like traditional hunting binoculars. This reduces eye strain during long observation sessions, provides better depth perception and spatial awareness, and leaves your hands free for weapon handling or navigation. The QUEST-S50R's dual-eyepiece design with independent diopter adjustment means each eye gets a sharp, full-resolution image tuned to your vision—critical when you're identifying targets in low light.
The binocular has a detection range of 2850 yards, achieved through the combination of the 1280×1024 high-resolution sensor, 50 mm f/1.1 objective lens, and 15 mK NETD thermal sensitivity. The integrated 1000-yard laser rangefinder gives you precise distance to targets you've already identified, but thermal detection can extend well beyond that distance depending on target size and thermal signature.
The QUEST-S50R ships with an adjustable binocular harness designed to distribute weight and allow hands-free operation during extended field use. Power is provided via an internal USB-C rechargeable battery with support for standard 18650-style auxiliary batteries for backup or extended missions.
Yes. Each eyepiece has independent diopter adjustment, allowing you to fine-tune the focus to your individual vision in each eye. The dual AMOLED displays deliver full resolution (1920×1200) to both eyepieces simultaneously, ensuring a sharp, comfortable image for extended scanning sessions.
