Apex Thermal 640 50mm Riflescope
Description
The Alpen Apex Thermal 640 50mm Riflescope is a professional-grade thermal optic built for hunters who demand peak performance in any condition - day or night, rain or shine. Featuring a 640x512 thermal sensor with an exceptional sensitivity rating of 18 mK or less, it detects the slightest temperature differences to produce crisp, low-noise imagery at distances up to 2,600 meters. Whether you're navigating dense foliage, zero-light environments, or challenging weather, this riflescope gives you a decisive edge over your target.
Built on a rugged, waterproof, and shockproof platform, the Apex Thermal 640 pairs cutting-edge thermal detection with a high-resolution OLED display and six selectable color palettes - black hot, white hot, green, iron hot, red hot, and sepia - so you can tune your view to any environment. Recoil-activated video recording, 64GB of internal storage, and built-in Wi-Fi for live streaming round out a feature set that sets this scope apart from the competition.

FAQ
Can this scope be used during the day as well as at night?
Yes - the Apex Thermal 640 is a full-time thermal imaging scope, meaning it detects heat signatures rather than relying on visible light. This makes it equally effective during daylight hours, at dusk and dawn, and in total darkness, as well as through fog, smoke, or dense foliage where traditional optics fall short.
How does the hot swap battery system work?
The scope features an internal rechargeable lithium battery that serves as a backup power source. When your external CR123A battery runs low, you can remove and replace it while the internal battery keeps the scope running - no need to power down, re-zero, or interrupt your hunt.
What is the difference between the 35mm and 50mm models?
The primary difference is detection range and light-gathering capability. The 35mm model detects targets up to 1,800 meters and is a lighter, more compact option. The 50mm model extends detection to 2,600 meters and delivers greater image clarity at long distances, making it the preferred choice for open-country or long-range hunting situations.
Does the scope record video automatically when I shoot?
Yes. The Apex Thermal 640 features recoil-activated video recording, which means it automatically begins capturing footage when it detects the recoil of a shot. All recordings are saved to the 64GB of internal storage for later review.
What color palettes are available on the OLED display?
The scope offers six selectable color palettes: black hot, white hot, green, iron hot, red hot, and sepia. Each palette renders thermal imagery differently, allowing you to choose the contrast and color style that best suits your environment and personal preference.
Is this scope compatible with standard rifle mounts?
The Apex Thermal 640 is designed to mount on standard rifle platforms. For the most accurate fit, we recommend verifying your ring and rail specifications before purchasing. If you have questions about compatibility, feel free to contact us for guidance.
