The Alpen Optics Apex 640 50mm Thermal Clip-On transforms your existing day scope into a full-featured thermal optic with built-in laser rangefinding — a combination rarely found below $3,500. The Apex delivers 640x512 thermal resolution and precise distance measurement to 1,000 meters without sacrificing your existing zero or requiring a second scope. At $2,999, it undercuts competing 640-resolution clip-ons with integrated LRF by $700 or more while matching them on core sensor performance.


Key Features
  • 640x512 thermal sensor with 12µm pixel pitch — High-resolution thermal imaging with ≤18mK NETD sensitivity detects heat signatures out to 2,600 meters, revealing game concealed in heavy brush, fog, or complete darkness. The 50mm objective lens gathers ample infrared energy for crisp detail even at extended distances
  • Integrated laser rangefinder to 1,000 meters — Get instant, precise distance measurements without carrying a separate rangefinder or breaking cheek weld. Most competing clip-ons in this price range omit LRF entirely, making this a standout feature for hunters who need both thermal detection and accurate ranging in a single device
  • 1920x1080 OLED display — Full HD viewing through your existing day scope eyepiece with six selectable color palettes: black hot, white hot, green, iron hot, red hot, and sepia. Choose the palette that provides the best contrast for your environment — iron hot and sepia often excel in dense vegetation, while white hot offers the most intuitive scanning view
  • Magnesium alloy construction at 580g — Rugged enough for backcountry hunting while keeping total system weight manageable. Waterproof and shockproof with a 1,000g recoil rating without losing zero
  • Sub-pixel zeroing technology — Achieves zeroing accuracy under 0.9cm at 100 meters, ensuring your thermal point of impact aligns precisely with your day scope's crosshairs
  • Recoil-activated video recording — Automatically captures footage when recoil is detected, documenting every shot on the built-in 32GB internal storage without fumbling for a record button mid-hunt
  • Wi-Fi streaming and Bluetooth control — Live-stream your thermal view to a phone or tablet for spotting partners, and operate the unit remotely via Bluetooth — useful when the shooter needs to stay focused on the target while a spotter monitors the thermal feed
  • Dual 18650 battery system — The dual 18650 battery system delivers up to 15 hours of combined runtime. The quick-release battery cover allows field swaps in seconds, and individual battery life is approximately 6 hours — enough for a full night of hunting without interruption

Who It's For

Predator hunters who've invested in a quality day scope and want to extend it into darkness without re-zeroing or remounting. The clip-on design preserves your existing scope setup — attach, power on, and your day scope becomes a thermal scope.

Hog hunters working after dark where thermal detection is essential and knowing exact range prevents wasted shots on animals beyond ethical distance. The integrated LRF means one less piece of gear to carry and one fewer step before the shot.

Budget-conscious thermal buyers stepping up from 384 or 256-resolution devices who want 640-class image quality with a built-in rangefinder. Competing 640-resolution clip-ons with LRF — like the Guide TB650 PRO and AGM Rattler V3 LRF — start at $3,700 and $5,300 respectively, positioning the Apex as strong value in the LRF clip-on segment.

Coyote and varmint hunters who need to quickly identify and range targets across open terrain. The 2,600-meter detection range and 50mm objective provide the reach for scanning wide fields, while the 8.7° field of view keeps the image wide enough to track moving targets.


Compatibility & Setup

The Apex 640 is a clip-on thermal compatible with riflescopes up to 10x magnification. With a 6-meter close focus distance and 30mm eye relief, it provides comfortable viewing through your existing day scope's eyepiece.

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!

That it’s usable for more than one day
Color: A3-Pink, Color: A3-Pink
The toy itself is great and my puppy enjoyed it. My problem is that it didn’t come with a charging cord and none of mine fit. It never changed colors. Maybe if I had a charger cord it would be worth it, but right now it’s useless!!

Fun for Fido but flimsy
Color: A2-Blue
My 15 yearold mini Schnauzer, Sam, played with this for less than 1 hour and tore the rubber sleeve off it. I will say the toy itself is a genius idea. Sam was absolutely ensconced. I wish it were made sturdier.
