Description
The Athlon Cronus ATS 50-640 is a thermal riflescope from Athlon Optics with a 640×480 sensor and a fast 50 mm F1.0 germanium lens, built in a traditional 30 mm tube design. It is the top model of the Cronus ATS range, pairing a 640 sensor with a 50 mm lens for long-range detail.
Why choose the Athlon Cronus ATS 50-640
The 640×480 sensor and sensitivity of 25 mK or better give a crisp, detailed picture, and the 50 mm lens extends detection well beyond normal hunting distances. Athlon’s 1440×1080 display is sharper than many competitors, which makes it easier to judge what you are looking at.
Key features
- 640×480 or 400×300 sensor with 12 µm pixels and sensitivity of 25 mK or better for clean, sharp images.

- Auto-shot recording that starts video when the scope detects recoil.

Choosing the right thermal scope
Start with the distances you usually shoot. A 384 sensor suits most hunting at typical ranges, while a 640 sensor shows more detail and helps you identify animals further away. A larger lens gives more reach, but a smaller lens gives a wider field of view for scanning. Also think about battery life, weight and whether you want a built-in rangefinder. If you need help comparing models, contact our team before you order.
