Here's the direct answer before you scroll further: in the current ATN lineup, there is no 1280-resolution thermal rifle scope. The 1280×1024 sensor — the highest-resolution thermal chip ATN builds — lives in the BlazeHunter XD LRF, a handheld thermal monocular, not a scope you mount on a rifle. If you searched for a "1280 thermal scope" expecting a riflescope, this is the honest starting point: on scopes, 640×512 is the current ceiling. This guide explains where the 1280 sensor actually sits in the lineup, why that split exists, and what to buy depending on whether you need a scanning tool or a shooting optic.
1280×1024 means 1,310,720 pixels reading temperature — about four times the count of a 640×512 sensor. ATN puts that sensor in the BlazeHunter XD LRF monocular for long-range scanning and identification, not in a rifle scope. If you need to put a reticle on an animal and pull a trigger, the ThOR 6 640 2-16x, at 640×512, is the highest-resolution scope ATN currently makes.
Quick Answer: Where 1280 Resolution Lives at ATN
- Best 1280 device overall: ATN BlazeHunter XD LRF 1280 (TIMNBLH1250LRF) — the only 1280×1024 thermal device in the ATN lineup, built as a handheld monocular with a laser rangefinder
- Best for scanning before the shot: BlazeHunter XD LRF — 3400 m detection range, ideal for glassing a field before you move to a rifle
- Best 1280-adjacent value: BlazeHunter XD LRF's 1000 m built-in laser rangefinder, which most 640 scopes don't include standard
- Best rifle scope if you need to shoot, not just scan: ATN ThOR 6 640 2-16x (TIWST6635A) — 640×512, the highest resolution ATN currently puts on a scope
- Best pairing for a complete night setup: BlazeHunter XD LRF in hand plus the ThOR 6 640 2-16x on the rifle — scan wide, then shoot with the dedicated optic
Why the Latest Generation of Thermal Sensors Stands Out
Resolution and NETD are two separate specs, and both come from the same 6th-generation sensor engine ATN uses across its current lineup. Resolution is pixel count — how many individual temperature readings make up the image. NETD (Noise Equivalent Temperature Difference) is sensitivity — how small a temperature difference the sensor can distinguish from noise, measured in milliKelvin. A high-resolution sensor with weak NETD still looks grainy; a low-resolution sensor with excellent NETD still looks blocky at distance. The current generation pairs both: the BlazeHunter XD LRF's 1280×1024 sensor runs at ≤15mK NETD on a 12μm pixel pitch, and the ThOR 6 640×512 scopes hit that same ≤15mK figure. That's why the meaningful comparison in this guide isn't "1280 versus 640" in the abstract — it's device format. A monocular can afford the biggest sensor and largest lens because it doesn't need to survive rifle recoil or fit a reticle. A scope has to do both, which is part of why ATN's highest scope resolution currently tops out at 640×512.
Comparison Table: 1280 and the Highest-Resolution 640 Scope
| Model | Format | Sensor | NETD | Magnification | Detection Range | Battery Life | Weight | Price |

Best 1280 Device: ATN BlazeHunter XD LRF
The BlazeHunter XD LRF is the only place in the current ATN catalog where you'll find a 1280×1024 sensor, and it's built for exactly what a monocular is good at: long, careful scanning, not shouldering a rifle.
Image Quality
1280×1024 resolution on a 12μm pixel pitch with ≤15mK NETD gives this sensor over a million individual temperature-reading points — roughly four times the pixel count of a 640×512 chip. Think of it like the difference between reading a page printed at four times the dot density: at the same viewing distance, fine detail that would blur into a single smudge on a lower-resolution sensor stays separated and readable. SharpIR© AI processing adds real-time sharpening and contrast enhancement on top of that base resolution.
Range & Magnification
A 50mm germanium lens and 2-16x magnification (with 8× digital zoom on top) pair with a 3400 m detection rating — the longest detection distance of any device in this comparison. The built-in laser rangefinder reads to 1000 m with ±1 m accuracy, which is a genuinely useful pairing with the sensor: you spot something at distance, then get an exact range on it without switching tools.
Battery & Build
Two replaceable 18650 batteries deliver 10+ hours of combined runtime, and the whole unit weighs just 495 g (1.1 lb) without battery — light enough to carry all night without the fatigue a rifle-mounted optic would cause over the same hours. Magnesium alloy housing and IP67 sealing hold up to the same field conditions as ATN's scope line.
Smart Features
Wi-Fi connects to the ATN Connect 6 app for live-view streaming, and onboard recording captures video and audio to 32 GB of internal storage. Six color palettes — White Hot, Black Hot, Ironbow, High Red, Green Hot, and Sepia — let you match the display to conditions, the same palette set available across ATN's current-generation devices.
Buy this if you want the sharpest possible thermal image for scanning, scouting, or identifying game at distance before you commit to a shot. Skip it if you need to mount an optic on a rifle — this is a handheld device, not a scope, and it has no reticle.
Best Rifle Scope If You Need to Shoot, Not Just Scan: ATN ThOR 6 640 2-16x
If your search for a "1280 thermal scope" is really a search for the sharpest thing you can shoot through, this is where that search ends inside the current ATN lineup.
Image Quality
640×512 resolution at ≤15mK NETD is the ceiling for ATN rifle scopes today. It's a quarter of the pixel count of the BlazeHunter XD LRF's sensor, but it's paired with a reticle, recoil-rated housing, and the ballistic tools a monocular doesn't need.
Range & Magnification
2-16x optical magnification with 8× digital zoom and a 3100 m detection rating cover the range where most rifle shots actually happen. For longer engagement distances, the ThOR 6 640 3-24x steps the optical range up with a 50mm lens and a 3650 m rating.
Battery & Build
Dual 18650 batteries run about 9 hours, and the 830 g (1.83 lb) magnesium alloy housing carries a 6000-joule recoil rating — built specifically to survive being fired on top of, which the BlazeHunter XD LRF was never designed to do.
Smart Features
Zeroing Freeze, Picture-in-Picture, Hot Point Tracking, and Recoil Activated Video are all reticle-and-trigger features that a scanning monocular doesn't need and doesn't have.
Buy this if you need an optic that goes on the rifle and holds zero through recoil. Skip it if pure image resolution for scanning matters more to you than shooting through the device — the BlazeHunter XD LRF outresolves it by a wide margin.
How to Choose Between 1280 and 640
Start with what the device needs to do. If you're scanning a field, a fence line, or a treeline to find and identify an animal before you ever raise a rifle, the BlazeHunter XD LRF's 1280×1024 sensor gives you more detail at distance than any scope in the lineup, plus a rangefinder to confirm distance once you've spotted something. If the device needs to sit on top of a rifle and hold a reticle through recoil, a monocular isn't an option regardless of its sensor — you need a dedicated scope, and 640×512 is the current ceiling there.
Consider terrain and typical engagement distance next. Open ground at moderate range rarely demands more than 640×512 resolution paired with strong NETD — the ThOR 6 640 line handles that comfortably. Long glassing sessions over big country, where you're trying to pick a distant heat signature out of a huge field of view, are where the extra pixel density of the 1280 sensor earns its keep.
Weight adds up differently depending on how you carry the device. A monocular rides in a hand or on a chest harness and doesn't affect rifle balance, so the BlazeHunter XD LRF's weight matters less than a scope's. A rifle scope's weight changes how the gun points and swings, which is one more reason ATN builds its scope line around a lighter sensor footprint than its top monocular.
Budget is the last filter, and it's a real one here — the BlazeHunter XD LRF is priced above the ThOR 6 640 2-16x. If your plan is a single all-purpose device, decide first whether you'll spend more time scanning or more time shooting, because that answer points you to the right format before price even enters the decision.
FAQ
Does ATN make a 1280 thermal rifle scope?
No. The only current ATN device with a 1280×1024 sensor is the BlazeHunter XD LRF, which is a handheld thermal monocular, not a rifle scope. ATN's highest-resolution rifle scope currently uses a 640×512 sensor.
What is the most expensive thermal scope ATN sells?
Among dedicated rifle scopes, the ThOR 6 LRF 640 3-24x is the top-priced model at $4,945.00, combining the 640×512, ≤15mK sensor with a built-in laser rangefinder and ballistic calculator.
Why would a monocular have a higher resolution than a rifle scope?
A monocular doesn't need to survive recoil, hold a reticle, or fit inside the size and weight limits of a rifle-mounted optic, which gives engineers more room to prioritize sensor size and lens diameter for maximum image detail.
Is 1280×1024 resolution actually better than 640×512 for hunting?
It carries roughly four times the pixel count, which shows up as finer detail at long distance or in cluttered terrain. For typical rifle-shooting distances, a well-built 640×512 sensor with strong NETD is usually enough that the difference isn't the limiting factor.
Can I mount the BlazeHunter XD LRF on a rifle?
No. It's designed and built as a handheld monocular with no reticle and no recoil rating, so it isn't intended for rifle mounting. For a rifle-mounted optic, choose from ATN's ThOR 6 scope line.
What does the laser rangefinder on the BlazeHunter XD LRF measure?
It reads distance out to 1000 m with ±1 m accuracy, using an eye-safe 905 nm Class 1 laser — useful for confirming range on something you've already spotted through the thermal sensor.
Should I buy a 1280 monocular or a 640 scope first?
It depends on your current gear. If you already have a thermal scope and want a scanning tool to find targets faster, the BlazeHunter XD LRF adds that capability. If you have no thermal optic at all and need to shoot through it, start with a dedicated scope like the ThOR 6 640 2-16x.
The Bottom Line
If you came here looking for a "1280 thermal scope," the honest answer is that ATN doesn't build one — the 1280×1024 sensor lives in the BlazeHunter XD LRF, a handheld monocular built for scanning and identification at distance, not for mounting on a rifle. For shooting, the ATN ThOR 6 640 2-16x is the highest-resolution scope currently in the lineup, and pairing the two devices — BlazeHunter XD LRF for scanning, ThOR 6 for the shot — is how you get the full benefit of both sensor classes in one setup.
