Thermal Imager PULSAR Telos LRF XL50 50 mm lens 640×480 resolution

The PULSAR Telos LRF XL50 50 mm lens 640×480 resolution is a thermal imager designed for long-range observation and detection. Equipped with a 50 mm objective and a 640×480 thermal sensor, the device produces detailed heat images suitable for outdoor surveillance, wildlife monitoring and search operations. An integrated laser rangefinder (LRF) provides distance measurements to observed targets, supporting precise situational assessment and improved target identification in low-visibility conditions.

Advantages

The combination of a 50 mm lens and a 640×480 thermal sensor delivers higher image detail at extended ranges compared with smaller optics, improving the ability to detect and recognize heat sources. The built-in laser rangefinder adds metric distance information directly to the thermal view, reducing the need for separate rangefinding equipment. Rugged construction and weather-resistant design make the unit suitable for outdoor use across varied environments, and the unit’s user interface is arranged for efficient operation in the field.

Suitable for

• Long-range wildlife observation and nocturnal animal monitoring
• Search and rescue operations in low visibility
• Perimeter surveillance and security patrols
• Field reconnaissance and tactical observation

Key specifications

• Optical configuration: 50 mm objective lens optimized for long-range thermal imaging
• Sensor resolution: 640 × 480 thermal detector for detailed heat signatures
• Integrated laser rangefinder for direct distance measurement to targets
• Imaging mode: thermal (heat-based) visualization suitable for day and night use
• Ruggedized housing with weather resistance for outdoor operation

How to use

Power on the thermal imager and allow the sensor to stabilize following the manufacturer’s warm-up guidance. Use the optics to frame the target, then activate the live thermal view to identify heat sources. Press the rangefinder control to obtain distance measurements and combine this information with the thermal image for target assessment. Adjust image settings such as digital zoom, palettes or contrast as needed to optimize visibility in specific conditions. Follow safe handling practices and keep lenses and sensors clean for best image quality.

Usage recommendations

For extended field deployments, carry spare batteries or approved external power sources and use a stable support or tripod when performing precise observation or rangefinding at long distances. Regularly inspect seals and connectors for moisture ingress, and store the device in a protective case when not in use to preserve performance.
