The Alpen Apex 640 50mm Thermal Riflescope pairs a 640x512 sensor with ≤18mK NETD sensitivity and 2,600-meter detection range — delivering sharp thermal imaging and long-distance target acquisition for hunters who operate in complete darkness. The 1440x1080 OLED display renders clear detail across the full 2.78x to 22.2x magnification range, and features like Forest Mode, Picture-in-Picture, and a built-in ranging system go beyond basic thermal viewing into active hunting tools.

Key Features

• 640x512 thermal sensor with 12µm pixel pitch — ≤18mK NETD sensitivity detects heat signatures out to 2,600 meters. The 50mm objective lens provides a wide 8.7° field of view at base magnification, narrowing to 6.98° at higher zoom levels

• 1440x1080 OLED display with six color palettes — High-resolution viewing with Black Hot, White Hot, Green, Iron Hot, Red Hot, and Sepia modes. Alpen's Clear+ image processing technology optimizes sharpness and contrast across conditions

• 2.78x base magnification with up to 8x digital zoom — Scan at wide field of view or zoom to 22.2x total magnification for target identification at range, controlled through a single rotary dial

• 30+ reticle patterns in three colors — Choose from over 30 reticles in White, Red, or Green. Multiple zeroing profiles with freeze-image zeroing allow precise adjustments and quick transitions between setups

• Forest Mode, Hot Point tracking, and Picture-in-Picture — Forest Mode enhances high-temperature targets against warm backgrounds. Hot Point marks the highest temperature in the field of view in real time. PIP magnifies the reticle area in a corner overlay without narrowing your overall view

• Built-in Ranging Mode and compass — The Ranging Mode estimates distance to targets using preset profiles for wolf, rabbit, wild boar, and deer. A 3-axis calibrated compass provides heading reference directly in the display

• Recoil-activated video recording with 64GB storage — An impact sensor detects recoil and automatically records video, capturing every shot hands-free. The built-in microphone records audio (toggleable), and 64GB of internal storage holds hours of footage. Export via USB-C or review directly on the scope

• Hot-swap battery system — An internal rechargeable lithium battery provides up to 6 hours of runtime, with a CR123A backup that keeps the scope powered during battery changes. Charge via USB-C

• Wi-Fi streaming and companion app — Stream your thermal view live over 2.4 GHz Wi-Fi to a phone or tablet for spotting or review. The companion app supports OTA firmware updates

• Built for extreme conditions — Waterproof and shockproof construction with an operating range of -30°C to +55°C (-22°F to +131°F). The frost-resistant display maintains performance in sub-zero temperatures

Who It's For

Predator and hog hunters working after dark who need reliable thermal detection. The 2,600-meter detection range and 50mm objective provide reach for scanning wide areas, while six color palettes and Forest Mode let you optimize for your specific terrain — whether open fields or dense tree canopy.

Hunters who record their hunts for review, training, or sharing. Recoil-activated recording eliminates the need to press a button before the shot, and 64GB of storage means space for multi-night trips. Wi-Fi streaming lets a spotter follow along on a phone in real time.

Shooters upgrading from 384 or 256-resolution thermals who want a meaningful step up in image clarity and detection range. The 640x512 sensor and ≤18mK sensitivity deliver noticeably sharper target definition than lower-resolution sensors, and the 1440x1080 display makes the difference visible.

Hunters in extreme conditions who need gear rated for the worst weather. Operating from -30°C to +55°C with waterproof construction, hot-swap batteries, and a frost-resistant display, the Apex handles late-season cold, humid nights, and extended sits in total darkness.
