RIX Optics STRIDE ST6 Lite Thermal Imaging Monocular
– 640×512 Sensor, 1x Magnification, and Suitable for Head and Vehicle Mounting

The RIX Optics STRIDE ST6 Lite was developed for hunters, game wardens, and serious outdoor enthusiasts who want to combine thermal imaging with maximum freedom of movement. Featuring a high-quality 640×512 thermal imaging sensor, true 1x base magnification, a wide field of view of 17.5° × 13.1°, and a weight of just 205 grams, this compact thermal imaging monocular delivers a remarkable amount of detail without feeling bulky or tiring.

This makes the STRIDE ST6 Lite more than just a lightweight thermal imaging monocular. Thanks to its compatibility with head, helmet, and vehicle mounts, it can be used for hands-free observation, nighttime terrain reconnaissance, wildlife detection, patrols, and search operations. Whereas simple, compact thermal imagers primarily show heat sources, the ST6 Lite—thanks to its high sensor resolution—provides significantly more useful information about shape, position, and movement.

640×512 thermal imaging sensor for visibly greater detail

At the heart of the RIX Optics STRIDE ST6 Lite is a 640×512 thermal sensor with a pixel pitch of 12 μm. This high resolution provides more image information than a 384×288 sensor, allowing contours, body shapes, and small temperature differences to remain visible with greater accuracy.

You’ll notice this difference most when an animal is partially hidden behind vegetation, moving at a medium distance, or barely stands out against a damp background. Greater sensor detail helps you distinguish more quickly between game, livestock, vegetation, and other heat sources.

The NETD value of less than 20 mK increases thermal sensitivity. As a result, the image remains usable in rain, fog, high humidity, and low temperature differences—conditions in which less expensive thermal imaging devices often display flat or poorly defined images.

Key Sensor Performance Specifications

• 640×512 thermal imaging sensor
• Pixel pitch of 12 μm
• NETD <20 mK
• Frame rate of 50 Hz
• Detection range up to 1,300 meters
• High level of detail even with low thermal contrast

Weighs just 205 grams for extended and portable use

A thermal imaging monocular designed for tracking movement must be light enough to actually be worn for hours at a time. The STRIDE ST6 Lite weighs only 205 grams and measures 129 × 71 × 47 millimeters.

That low weight makes a noticeable difference when used on a helmet or head mount. Heavier thermal monoculars are more likely to cause pressure on the neck and head, especially when worn with a mount and other gear. The ST6 Lite remains compact and well-balanced, making extended use more comfortable.

Even as a handheld device, it’s easy to carry in a jacket pocket or compact gear bag. This keeps it within reach when you need thermal vision quickly.

True 1x magnification for natural situational awareness

The STRIDE ST6 Lite starts at 1x magnification, displaying the surroundings in a natural scale. Objects do not appear unnaturally close, and movements feel more immediate than with thermal imaging devices that start at 2x or 3x by default.

This is especially relevant during:

• Nighttime travel through forests and open terrain
• Head-mounted use
• Patrols and Terrain Surveillance
• Search Results
• Observation from a vehicle
• Game detection at short and medium ranges

For mobile use, a broad view is more important than maximum magnification. The 1x magnification helps you interpret distances, obstacles, and moving heat sources more quickly and naturally.

Wide field of view for faster scanning

With a field of view of 17.5° × 13.1°, the STRIDE ST6 Lite displays a large portion of the terrain at once. This reduces the need to constantly move your head or hand back and forth.

When scanning the edge of a forest, a wild meadow, a trail, or a yard, this increases the likelihood that movement will be detected immediately. A narrower field of view sometimes offers greater magnification but limits the overall view. The ST6 Lite deliberately opts for a wide thermal image that is better suited for reconnaissance, navigation, and continuous observation.

25 mm F1.0 lens for a balance between field of view and range

The 25 mm F1.0 lens pairs well with the 640×512 sensor. The lens provides sufficient range for detection up to 1,300 meters, while maintaining a wide field of view.

This makes the STRIDE ST6 Lite suitable for a wide range of distances. At close range, you maintain a clear overview, while at medium and longer ranges, sufficient detail remains available to accurately assess heat sources.

Compared to larger lenses, the housing remains compact and lightweight. This makes the viewer more suitable for primary use and mobile applications without sacrificing an excessive amount of thermal performance.

Optical Specifications

• 25 mm F1.0 lens
• Magnification from 1x to 6x
• Digital zoom from 1x to 4x
• Field of view: 17.5° × 13.1°
• Detection range up to 1,300 meters
• Diopter adjustment from -5D to +5D
• 20 mm eye relief

Smooth image while walking and observing

The 50 Hz frame rate ensures a smooth and steady image. This is especially important when the device is worn on the head or used from a moving vehicle.

At a lower refresh rate, the image may appear choppy while turning or walking. The ST6 Lite processes movement quickly, making it easier to keep track of terrain, obstacles, and animals.

This not only improves viewing comfort but also helps you make decisions faster during active observation.

1024×768 high-contrast OLED display

The image is displayed on a 1024×768 OLED screen. OLED technology is known for its deep blacks and high contrast, which clearly distinguish between hot and cold areas.

This makes small differences in contours more visible and keeps menus and measurement data in sharp focus. Even during prolonged observation, the image remains stable and clear.

The adjustable diopter allows you to precisely adjust the focus to suit your individual vision.

Six color palettes for different conditions

The STRIDE ST6 Lite features six color palettes. This allows you to adjust the thermal display to suit the terrain, weather conditions, and your personal preferences.

A high-contrast color palette helps you quickly locate heat sources. A more subdued palette, on the other hand, can be more comfortable during extended viewing or when mounted on a head-mounted device. By selecting the right display mode, you can reduce eye strain and ensure more consistent image interpretation.

1x to 6x magnification for flexible observation

With an adjustable magnification range from 1x to 6x, you can easily switch between a wide overview and a more focused inspection.

At 1x magnification, the viewer is ideal for navigation, searching, and situational awareness. At higher magnifications, you can examine a heat source more closely without having to change your position immediately.

Digital zoom cannot create new sensor details, but thanks to the high 640×512 resolution, the image remains more usable when zoomed in than with compact binoculars that have a lower sensor resolution.

Suitable for head and helmet mounting

The STRIDE ST6 Lite comes with adapter parts and features mounting options for compatible head and helmet mounts.

When used hands-free, both hands remain free for handling equipment, navigation, searching, or other tasks. The combination of light weight, 1x magnification, and a wide field of view makes this model particularly well-suited for extended use on the head.

For optimal comfort, it is important to properly adjust the eye position, balance, and mounting height.

Thermal imaging from a vehicle

With a suitable vehicle mount, the STRIDE ST6 Lite can be used as a compact thermal observation system during nighttime travel, terrain reconnaissance, or search operations.

Thermal imaging technology does not rely on visible light and makes people, animals, and other heat sources visible in complete darkness. This provides earlier detection of movements beyond the range of normal lighting.

Thermal imaging remains a supplementary tool and is no substitute for direct vision or responsible driving.

Capture photos and videos instantly

The built-in recorder captures photos and videos at a resolution of 1024×768 pixels. The files are saved to the 32 GB internal memory in MP4 and JPG formats.

With it, you can, among other things:

• Documenting wildlife sightings
• View past search campaigns
• Capturing Field Conditions
• Analyzing Animal Activity
• Share images with colleagues or other observers

The built-in recording function eliminates the need for a separate camera system.

Wi-Fi for live video and wireless management

The STRIDE ST6 Lite supports Wi-Fi and can be connected to a compatible smartphone. Depending on the app’s functionality, you can view live images, transfer files, and manage firmware or settings.

This is useful when multiple people want to view the same thermal image or when the viewer is used in a fixed position or mounted on a vehicle.

Replaceable 18650 battery and USB-C power supply

The thermal imaging monocular runs on a replaceable 18650 battery and offers a runtime of up to approximately four hours at 25°C.

A removable battery offers more flexibility than a system that relies solely on an internal battery. With a spare battery, you can immediately extend the operating time without having to charge the viewer first.

The device can also be powered via USB Type-C by an external 5V power source, such as a compatible power bank.

IP67 protection for serious outdoor use

The housing meets the IP67 rating and is protected against dust, rain, and temporary submersion. The STRIDE ST6 Lite operates within a temperature range of -20°C to +50°C.

This makes it suitable for damp fall nights, winter observations, and dusty summer conditions. Its light weight does not compromise the protection needed in the field.

Practical use cases

Detecting wildlife along forest edges

The wide field of view helps you quickly scan large areas of terrain. The 640×512 sensor then makes it easier to distinguish animals from warm rocks, tree stumps, or vegetation.

Nighttime Terrain Reconnaissance

With 1x magnification, you can move more naturally through dark terrain. Obstacles, animals, and people become visible without the need for active lighting.

Long-term use on a helmet

Weighing just 205 grams, it minimizes strain on the head and neck. This makes the viewer more practical during longer patrols or search operations.

Observation from a vehicle

Its compact housing and mounting compatibility make the ST6 Lite ideal for mobile terrain surveillance and thermal observation on the go.

As a lightweight second thermal imager

The STRIDE ST6 Lite is a great complement to a larger long-range scope or thermal imaging rifle scope. You can use it for detection and navigation, while the larger optics remain available for identification or targeted use.
