Pulsar Telos XG50 LRF Thermal Imaging Monocular
640×480, 12 µm, <40 mK NETD
The Pulsar Telos XG50 LRF is basically the top-tier version of the Telos handheld line—packing a 640×480 12µm sensor with ultra-sensitive performance (<20mK system NETD), a 50mm F1.0 lens, and a built-in laser rangefinder that gives instant, accurate distance readings out to around 1000m. It delivers serious detection capability up to about 2300m, but the real win is how clean and stable the image stays thanks to Pulsar’s processing and the smooth 50Hz refresh, especially when you’re scanning large areas for long periods. Add in the modular, upgradeable Telos platform and you’ve got a rugged, future-proof thermal spotter built for users who want maximum handheld performance without stepping into bulky binocular setups.

1. What resolution does it use?
It uses a 640×480 thermal sensor with a 12µm pixel pitch for strong long-range detail and target separation.
2. How sensitive is it in poor conditions?
It has a sensor NETD under 40mK, with system-level sensitivity around <20mK, which helps it pick out heat differences in fog, rain, and humidity.
3. What is the detection range?
It can detect targets out to approximately 2300 metres depending on conditions and target size.
4. Does it have a laser rangefinder?
Yes, it includes a built-in LRF with a measuring range of up to about 1000m and ±1m accuracy.
5. What magnification does it offer?
It provides 3.5–14x magnification, which is ideal for both scanning and longer-range identification work.
6. How does it differ from the non-LRF XG50?
You get integrated distance measurement, which makes target evaluation faster and more precise without needing a separate device.
7. Is the image quality better than older Pulsar monoculars?
Yes—especially in contrast handling and clarity at range, thanks to improved sensor sensitivity and processing.
8. How long does the battery last?
Up to around 8.5 hours using the LPS7i battery pack depending on conditions and settings.
9. Is it weatherproof?
Yes, it’s IPX7 rated, so it can handle heavy rain and harsh field conditions without issue.
10. What’s the main reason to choose the LRF version over standard Telos XG50?
It comes down to workflow—having instant ranging built in speeds up identification and reduces guesswork, especially at longer distances.
