RIX Optics STRIDE ST3 Lite Thermal Imaging Monocular
RIX Optics STRIDE ST3 Lite – Ultra-Lightweight Thermal for Mobility & Awareness
The RIX Optics STRIDE ST3 Lite Thermal Imaging Monocular is designed for users who prioritise mobility, comfort, and fast target detection. Combining a compact form factor with a high-sensitivity thermal sensor, it delivers reliable performance for scanning and situational awareness in complete darkness and challenging environments.
Engineered for both handheld and helmet-mounted use, the ST3 Lite is ideal for hunters, pest controllers, and outdoor users who need hands-free thermal capability without the weight of larger systems.
384 Thermal Sensor with High Sensitivity
At the core of the ST3 Lite is a 384×288 VOx thermal sensor, offering strong image clarity and sensitivity for its class.
- 384×288 resolution with 12µm pixel pitch
- NETD <20mK for detecting subtle temperature differences
- Smooth 50Hz refresh rate for fluid tracking
This allows for clear identification of heat signatures even in fog, darkness, or dense terrain.
Wide Field of View & True 1× Base Magnification
The ST3 Lite is optimised for scanning and movement:
- True 1× optical magnification for natural viewing
- Up to 6× magnification range
- Wide field of view for improved situational awareness
This makes it particularly effective for tracking moving targets and navigating terrain without losing depth perception.
Lightweight & Helmet-Mount Ready
One of the standout features of the ST3 Lite is its ultra-lightweight design:
- Approx. 6.7 oz (˜190g)
- Compact size for reduced fatigue
- Suitable for helmet-mounted or handheld use
Its low weight makes it ideal for extended sessions, especially when mounted for hands-free operation.
Detection Range for Practical Field Use
- Detection range up to ~780 metres / 852 yards
- Designed for short to mid-range scanning
- Ideal for woodland, farmland, and mobile hunting setups
This provides ample range for early detection before switching to a riflescope.
OLED Display, Recording & Connectivity
- 1024×768 OLED display for clear viewing
- Built-in photo and video recording
- Wi-Fi connectivity for mobile streaming
- Internal storage for saving footage
These features allow users to capture and review thermal observations in real time.
Durable & Field-Ready Construction
- IP67-rated waterproof and dustproof design
- Operates in harsh environments
- Powered by 18650 rechargeable battery
- Designed for outdoor reliability
