1280×1024 HD Thermal Sensor – Outstanding Image Detail

At the centre of the Pulsar Telos LRF XT50 is a high-definition 1280×1024 thermal imaging sensor manufactured in Europe.

With more than 1.3 million thermal pixels and a 12µm pixel pitch, this advanced sensor captures fine temperature differences and produces highly detailed thermal images.

The increased sensor resolution helps users observe animal shapes, distinguish movement and examine distant heat sources while maintaining useful image information at higher magnification.

Compared with conventional 640×480 thermal imaging sensors, the XT50 provides more than four times the total number of sensor pixels.

This additional resolution is particularly beneficial when scanning large areas, tracking wildlife and examining distant objects where image detail matters.

High Thermal Sensitivity Below 20 mK

The Telos LRF XT50 combines a sensor NETD rating below 40 mK with an enhanced system NETD below 20 mK.

The system’s thermal sensitivity helps reproduce subtle temperature variations, improving visible contrast between animals, vegetation and surrounding terrain.

This is especially valuable when observing in challenging conditions such as:

• Cold or humid environments
• Light rain and mist
• Low-contrast woodland areas
• Dawn and dusk
• Complete darkness

Thermal imaging detects emitted infrared radiation rather than relying on visible light. This allows the XT50 to locate heat sources during both daytime and nighttime observation.

Heavy rain, dense fog and reduced thermal contrast can still affect detection performance.

50mm F1.0 Lens and 2300m Thermal Detection Range

The Telos LRF XT50 features a 50mm F1.0 germanium objective lens designed to collect thermal radiation efficiently.

Working together with the HD sensor, the lens supports detailed thermal observation at long distances.

Pulsar specifies a maximum detection range of 2300 metres for a deer-sized target under suitable conditions.

This makes the XT50 suitable for scanning:

• Open fields and agricultural land
• Woodland boundaries
• Hillsides and valleys
• Large hunting grounds
• Wildlife habitats
• Remote outdoor areas

The 2300m figure represents thermal detection rather than guaranteed target identification. Recognition and identification distances depend on environmental conditions, target characteristics and the level of thermal contrast.

Wide 17.5° Field of View – Scan More Ground

One of the main advantages of the Pulsar Telos LRF XT50 is its wide 17.5° × 14° field of view.

At a distance of 100 metres, the monocular covers an observation area approximately 30.7 metres wide and 24.7 metres high.

The wide viewing angle helps users search large areas efficiently without repeatedly repositioning the device.

For hunting and wildlife observation, this means improved awareness of the surrounding environment and easier detection of moving animals.

The combination of 2x base magnification and a wide field of view makes the XT50 suitable for both close-range scanning and longer-distance observation.

Integrated 1200m Laser Rangefinder – Accurate Distance Measurement

The Pulsar Telos LRF XT50 includes a redesigned laser rangefinder integrated into a compact, low-profile housing.

The rangefinder measures distances up to 1200 metres with a stated accuracy of ±1 metre.

It supports both single-distance measurement and continuous scanning, helping users determine the distance to observed objects without carrying separate ranging equipment.

The system operates using a 905nm laser and meets Class 1 laser safety requirements.

Unlike earlier Telos LRF models with a 1000m measurement range, the XT50 extends the maximum ranging distance to 1200m.

The redesigned housing also incorporates a convenient 1/4-inch tripod mounting connection for stationary observation.

2–16x Magnification with Pulsar Zoom Boost up to 24x

The Telos LRF XT50 offers a versatile 2–16x magnification range.

At the minimum 2x setting, users benefit from the wide field of view when searching for animals or scanning terrain.

Increasing magnification allows closer examination of detected heat sources and improved assessment of distant objects.

Pulsar’s Zoom Boost feature extends the digital magnification range up to 24x.

The high-resolution sensor supports detailed viewing throughout the magnification range, while Zoom Boost offers additional digital enlargement when required.

Digital enlargement does not increase the native optical resolution of the sensor.

Electronic Image Stabilisation

Electronic image stabilisation is a valuable feature of the Telos LRF XT50, particularly during handheld observation at higher magnification.

The system helps compensate for small hand movements, reducing visible shaking and supporting steadier thermal images.

This makes it easier to follow moving wildlife and observe distant subjects without relying on a tripod.

Image stabilisation also improves viewing comfort during extended observation sessions.

Full HD 1920×1080 AMOLED Display

The Pulsar Telos LRF XT50 incorporates a high-resolution 1920×1080 AMOLED display.

Its Full HD resolution, deep black levels and strong image contrast help reproduce the detail captured by the thermal sensor.

The display provides comfortable viewing across different lighting conditions and supports detailed inspection of thermal images.

Users can select from nine thermal colour palettes to suit the observation environment and personal viewing preferences.

Picture-in-Picture Mode

Picture-in-Picture mode allows users to enlarge a selected section of the thermal image while maintaining visibility of the wider observation area.

A separate magnified window helps examine an object without losing the overall scene.

This is particularly useful when monitoring animal movement or inspecting distant heat sources while maintaining situational awareness.

Intuitive One-Handed Operation and Objective Ring Zoom Control

The Pulsar Telos series features a distinctive control arrangement inspired by professional camera optics.

Separate focusing and magnification rings are positioned around the objective lens, allowing smooth adjustments using one hand.

The controls provide convenient operation when scanning terrain, changing magnification or refining image focus.

A symmetrical button layout accommodates both left- and right-handed users.

Haptic feedback provides additional confirmation of supported control operations, making device handling more intuitive during outdoor observation.

The textured controls and rubber-coated housing help maintain a secure grip, including when wearing gloves or operating in wet conditions.

Replaceable LPS 7i Battery – Up to 8 Hours of Operation

The Telos LRF XT50 uses a removable Pulsar LPS 7i lithium-ion battery with a capacity of 6400mAh.

The manufacturer specifies an operating time of up to 8 hours at an ambient temperature of 22°C.

Battery duration depends on operating conditions, enabled functions and temperature.

The replaceable design allows users to carry additional batteries for extended field sessions.

Charging options include:

• USB Type-C charging
