Premium thermal binoculars with a 12 µm sensor and LRF
The Pulsar Merger LRF XL50 is a new-generation thermal binoculars that combines a 1024 × 768 @ 12 µm sensor, an F1.0 lens and a built-in laser rangefinder. High pixel density and improved thermal sensitivity offer clear advantages when observing at longer ranges — the image is detailed and the target stands out clearly against the background.
1024 × 768 @ 12 µm thermal sensor
A high-resolution 12 µm sensor system NETD < 20 mK with a resolution capable of detecting the finest temperature differences. The result is a sharper, higher-contrast thermal image in conditions ranging from cold winter mornings to warm summer evenings.
F50/1.0 lens and 2.5–20× magnification
The maximum aperture of F/1.0 captures the most thermal signal. 2,5 - 20× The smooth zoom function allows for both quick scanning and detailed examination.
Laser rangefinder, up to 1000 m
Built-in LRF measures distances up to 1000 metres with an accuracy of ±1 m. Single-measurement and continuous-scanning modes provide a reliable distance estimate for every observation.
Detection range: 2,300 metres
The large sensor and F/1.0 lens offer a detection range for human-sized objects up to 2300 m. This makes the XL50 a solid choice for open-field monitoring.
AMOLED HD display and 64 GB internal storage
The 1024 × 768 AMOLED HD screen ensures sharp detail at any zoom level. The built-in video and photo camera, combined with 64 GB of internal storage, allow you to capture hours of footage.
