The Hydra HS635R thermal scope from DNT Optics is a professional-grade multi-function thermal optic engineered for precision shooters, hunters, and field professionals who require advanced capability in a compact and rugged platform. This system integrates a laser rangefinder, onboard ballistic calculator, and ISR (Image Super Resolution) enhancement, making it one of the most technologically capable thermal optics in its class.
Designed as a 3-in-1 thermal weapon system, the Hydra HS635R functions as:
- A standalone thermal rifle scope
- A clip-on in front of LPVO or prism optics
- A handheld thermal monocular
Built around a 640×512, 12 μm ≤18mK thermal sensor and a 35mm germanium objective lens, it delivers high contrast thermal imaging and long-range detection capability. DNT’s proprietary ISR enhancement algorithm increases clarity during digital zoom, solving the common issue of thermal pixelation at higher magnification levels.
The Hydra chassis is CNC machined from a single block of 6061 aircraft-grade aluminum for durability and precise optical alignment. Rated IP67 waterproof and shock-resistant up to .50 BMG/800Gs, this optic is built for harsh field conditions. Power is supplied by interchangeable flat-top 18650 rechargeable batteries, providing extended runtime and easy field replacement.
Wireless connectivity via the DNT Optics App allows users to livestream, record, and share footage directly from the optic to a mobile device. The user interface is fast and intuitive, making the HS635R an efficient tool in dynamic hunting environments or applied shooting scenarios.
