Apex Thermal 640 35mm Riflescope
Description
The Alpen Apex Thermal 640 35mm Riflescope puts serious thermal imaging technology in the hands of hunters who demand performance in any environment, any time of day. Built around a high-resolution 640x512 thermal sensor with an impressive sensitivity of under 18 mK, this scope detects the slightest heat signatures from distant targets - letting you identify and engage threats invisible to the naked eye in total darkness, dense foliage, or adverse weather. The 35mm objective lens delivers detection distances out to 1800 meters, making it an outstanding choice for hunters who need reliable thermal coverage at mid-to-long range without the added bulk of a larger optic.
Results are rendered on a crisp OLED display with six color palette options - black hot, white hot, green, iron hot, red hot, and sepia - so you can dial in contrast for your specific conditions. Advanced image processing keeps the picture clean and low-noise, while multiple reticle patterns give you the versatility to set up exactly as your hunt demands. Recoil-activated video recording, 64GB of internal storage, and built-in Wi-Fi for live streaming round out a feature set designed for modern hunters who expect more from their gear.
Key Features
- 640x512 Thermal Sensor: High-resolution sensor with 12 µm pixel pitch captures fine thermal detail for precise target identification.
- NETD Sensitivity (≤18 mK): Exceptional sensitivity detects the slightest temperature differences, delivering crisp images even in challenging scenes.
- 1800m Detection Range (35mm): Impressive detection distance for a 35mm objective, giving you confident target acquisition at extended ranges.
- OLED Display (1440x1080): High-resolution screen maximizes contrast and delivers vivid imagery in six selectable color palettes - black hot, white hot, green, iron hot, red hot, and sepia.
- Recoil-Activated Video Recording: Automatically captures footage on the shot with 64GB of internal storage for reviewing hunts and shot placement.
- Built-In Wi-Fi: Stream live thermal video to your device for spotting assistance or remote monitoring in the field.
- Dual Power / Hot Swap System: Internal rechargeable lithium battery acts as backup power, allowing you to swap the external CR123A battery without powering down the scope.
- Multiple Reticle Patterns and Colors: Choose from a variety of reticle styles and colors to match your shooting setup and preference.
- Waterproof and Shockproof Construction: Rugged build handles demanding field conditions, recoil, rain, and rough handling without missing a beat.
- Digital Magnification (2.78x base, 1x/2x/4x/8x): Flexible zoom range lets you adapt from wide area scanning to close-in target focus on the fly.
Lens Options & Which to Choose
- 35mm Objective: A more compact and lightweight configuration that still delivers detection out to 1800 meters. Ideal for hunters working in tighter terrain, dense woods, or those who prioritize a lighter, more maneuverable setup without sacrificing core thermal performance.
- 50mm Objective: The larger lens gathers more thermal energy, pushing detection range out to 2600 meters. Best suited for open-country hunters, predator callers, and shooters who engage targets at longer distances and want maximum reach from their thermal optic.

FAQ
Can this scope be used during the day as well as at night?
Yes. Thermal imaging works by detecting heat signatures rather than visible light, so the Apex Thermal 640 performs effectively 24 hours a day. It is equally useful in bright daylight, low-light conditions at dawn and dusk, and complete darkness. This makes it a versatile tool for any hunting scenario regardless of time of day.
What is the difference between the 35mm and 50mm versions?
The primary difference is detection range and lens size. The 35mm model is more compact and detects targets out to 1800 meters, while the 50mm model's larger objective pushes that range to 2600 meters. If you hunt open terrain at long distances, the 50mm has the edge. For tighter environments or if you prefer a lighter, more manageable scope, the 35mm is an excellent choice.
How does the hot swap battery system work?
The scope has an internal rechargeable lithium battery that serves as a backup power source. When your primary external CR123A battery runs low, the internal battery takes over, allowing you to swap in a fresh CR123A without ever shutting the scope down. This means no lost time and no interruption to your hunt during battery changes.
What color palettes are available on the display?
The Apex Thermal 640 offers six selectable color palettes: black hot, white hot, green, iron hot, red hot, and sepia. Each palette renders heat signatures differently, so you can choose the one that provides the best contrast and visibility for your specific lighting and environmental conditions.
Does this scope record video, and how much footage can it store?
Yes. The scope features recoil-activated video recording that automatically captures footage when you fire a shot. It includes 64GB of internal storage, providing ample space for recording hunts and reviewing shot placement. You can also connect via Wi-Fi to stream live video to your own device in the field.
Is the Apex Thermal 640 waterproof?
Yes. The scope is built to be waterproof and shockproof, making it well-suited for demanding field conditions including rain, heavy humidity, and rough handling. It is also designed to withstand the repeated recoil of firearm use without compromising performance or zero.
