640 × 480 Thermal Imaging Sensor – Reliable Detection in Challenging Conditions

At the heart of the Pulsar SYMBION LRF DXR50 is an uncooled thermal microbolometer with a resolution of 640 × 480 pixels and a 12µm pixel pitch.

This thermal imaging sensor detects differences in infrared radiation emitted by objects, animals and the surrounding environment.

The technology allows users to locate heat signatures without relying on visible light.

The DXR50 is particularly effective for detecting animals in darkness, observing activity around woodland edges and searching across large areas where conventional optical binoculars become ineffective.

High Thermal Sensitivity – System NETD Below 18mK

The DXR50 features a thermal sensor NETD below 35mK and a system NETD below 18mK.

NETD, or Noise Equivalent Temperature Difference, indicates the ability of a thermal imaging system to distinguish small temperature variations.

Lower NETD values indicate greater thermal sensitivity.

With a system NETD below 18mK, the SYMBION DXR50 is designed to preserve subtle temperature differences within the observed scene.

This helps improve the separation of animals from their surroundings, particularly when the temperature difference between a subject and the background is limited.

The benefits are especially relevant during humid evenings, early mornings and changing weather conditions.

50Hz Thermal Image Refresh Rate

The 50Hz frame rate provides smooth thermal image updates when observing moving animals or scanning the landscape.

This improves viewing comfort and helps users follow movement across the field of view.

Powerful 50mm F1.0 Thermal Objective Lens

The DXR50 features a 50mm F1.0 germanium objective lens designed to deliver infrared radiation efficiently to the thermal sensor.

The combination of a 50mm lens and a 12µm thermal sensor produces a relatively narrow field of view with strong base magnification.

This optical configuration is particularly useful for observing distant objects across open terrain.

4–32x Thermal Magnification

The thermal channel offers magnification from 4x to 32x.

At its native 4x magnification, the binocular provides a detailed view of distant thermal signatures.

Digital magnification allows users to examine selected objects more closely.

Higher magnification is particularly useful for examining distant animals or individual areas of the landscape, although digital zoom does not add physical sensor detail.

Thermal Field of View

The thermal field of view measures:

• 8.8 degrees horizontally
• 15.4 metres at a distance of 100 metres

This narrower field of view prioritises the observation of distant subjects rather than scanning large areas at close range.

For hunters operating in open countryside, agricultural fields and extensive hunting grounds, the DXR50 provides an optical configuration suited to longer-distance observation.

Thermal Detection Range Up to 2300 Metres

The Pulsar SYMBION LRF DXR50 offers a stated thermal detection range of up to 2300 metres for a deer-sized object.

This allows users to detect a suitable thermal signature at considerable distances under favourable conditions.

Thermal detection should not be confused with animal identification.

Detection indicates that a heat-emitting object is present, while recognising its species and examining identifying details generally requires closer observation.

Actual performance depends on atmospheric conditions, temperature contrast, vegetation, target size and other environmental factors.

The DXR50 combines long-range thermal detection with a separate 4K digital channel to support more detailed observation when conditions permit.

4K Digital CMOS Sensor – Detailed Daytime and Twilight Observation

In addition to its thermal imaging system, the DXR50 integrates a 3840 × 2160-pixel digital CMOS sensor.

This 4K digital imaging channel provides an alternative to thermal observation when users need to examine visible details.

During daylight, it produces full-colour images suitable for studying terrain, identifying landmarks and observing wildlife.

In twilight conditions, the digital channel offers additional opportunities to examine animals and their surroundings.

For nighttime observation, the integrated infrared illuminator supports black-and-white digital viewing.

Digital Optical System

The digital channel features:

• Sensor resolution: 3840 × 2160 pixels
• Objective lens: 50mm F1.8
• Magnification: 6.5–26x
• Horizontal field of view: 5.8 degrees
• Field of view at 100 metres: 10.2 metres

The high base magnification makes the digital channel particularly suitable for examining subjects at a distance.

Why Combine Thermal and Digital Imaging?

Thermal imaging and digital imaging provide different types of information.

Thermal imaging is used primarily to reveal heat signatures and locate objects in darkness or visually difficult environments.

Digital imaging is designed to provide visible structural details, colours during daylight and high-contrast black-and-white observation at night with infrared assistance.

By incorporating both technologies, the DXR50 allows users to select the most suitable observation method for the situation.

Built-In 850nm Infrared Illuminator for Night Vision

The SYMBION LRF DXR50 incorporates an 850nm infrared LED illuminator.

Unlike thermal imaging, digital night vision depends on available or artificial infrared illumination when ambient light is insufficient.

The integrated illuminator provides additional infrared light for the digital channel, allowing observation in dark environments.

The illuminator features adjustable focusing and three power levels.

Users can adapt the illumination to the distance and conditions of the observation area.

This feature is useful when examining details that cannot be established using the thermal image alone.

Multispectral Picture-in-Picture – Thermal and Digital Imaging Together

One of the DXR50’s most useful functions is its multispectral Picture-in-Picture capability.

The system allows users to display information from both the thermal and digital imaging channels at the same time.

One image appears as the primary observation view, while the second channel appears in a smaller window.

For example, a hunter can locate an animal using thermal imaging while viewing the digital image to examine the visible surroundings.

This reduces the need to repeatedly switch between observation systems.

The feature supports faster interpretation of complex scenes, particularly when distinguishing between animals, vegetation and background objects.

Electronic Image Stabilisation

High magnification makes even small hand movements more noticeable.

The SYMBION DXR50 includes electronic image stabilisation designed to reduce the visible effects of hand movement.

This helps maintain a steadier image when observing distant animals or using higher magnification.

Image stabilisation is particularly valuable during extended handheld observation, when a tripod is unavailable or impractical.

The function also supports more comfortable tracking of moving subjects.

Integrated 1500m Laser Rangefinder

Accurate distance measurement is an important part of wildlife observation and hunting.

The Pulsar SYMBION DXR50 incorporates a laser rangefinder capable of measuring distances up to 1500 metres.

Laser Rangefinder Specifications

• Maximum measuring distance: 1500 metres
• Measurement accuracy: ±1 metre
• Laser wavelength: 905nm
• Laser safety classification: Class 1
• Single measurement and continuous scanning modes

The rangefinder allows users to determine the distance to an observed object without carrying a separate measuring device.

Continuous scanning is useful when examining several objects across a landscape or following movement.

The binocular also supports true horizontal distance indication, providing additional information when observing targets at an angle.

Range measurement performance depends on target reflectivity, object size and environmental conditions.

Integrated Ballistic Calculator and Connectivity

The DXR50 supports ballistic calculation features through its integrated software and compatibility with Stream Vision Ballistics.

This allows the device to form part of a broader observation and ballistic data workflow.

The system also supports compatible external ballistic information.

For hunters who already work with Pulsar equipment and software, this connectivity helps bring observation and range measurement information into one system.

Full HD AMOLED Display

The Pulsar SYMBION DXR50 features a 1920 × 1080 AMOLED display system.

The high-resolution display provides detailed image reproduction for both the thermal and digital observation channels.

AMOLED technology delivers strong contrast, deep black levels and clear separation between bright and dark areas.

This is useful for interpreting fine temperature differences in thermal mode and studying visible detail through the digital channel.

The binocular also provides adjustable display settings to suit observation conditions and personal preferences.

Photo and Video Recording with Sound

The SYMBION LRF DXR50 includes an integrated recording system for capturing observation sessions.
