ThermTec Ares 660L 2.0

• Dual field of view 20 mm/60 mm lens: Switch between a wide 21.7° view for scanning and a tighter 3.2x optical view for shot placement, so the scope adapts quickly as distances and terrain change.
• 640x512, 12 μm thermal sensor with ≤20 mK NETD: The sensor resolves small temperature differences more clearly, helping separate animals from background clutter in damp, cold, or low-contrast conditions.
• Integrated 1000 m laser rangefinder with ballistic calculation: Ranging and hold correction are built into the sight, reducing guesswork and speeding up decisions when targets are not at known distance.
• AMOLED display and onboard recording: The 1024×768 display gives a crisp viewing image, while photo and video capture let the user review sightings and zeroing sessions later.
• Long runtime with 18650 power system: Extended battery life and a field-friendly battery format make the Ares 660L 2.0 better suited to long outings where charging opportunities are limited.

About the ThermTec Ares 2.0 Series

The ThermTec Ares 2.0 series sits in the company’s thermal-imaging-sight range and was introduced on September 10, 2024 as a line built for hunters and night observation users who need a practical balance of image quality, field usability, and compact rifle-scope handling. The family includes both standard and LRF-equipped models, with the latter adding an integrated laser rangefinder and ballistic calculation for more confident distance work in the field.

A key characteristic of the series is its use of 12 μm uncooled thermal detectors combined with AI-assisted image calibration, a design intended to keep the image stable as environmental conditions shift. Within the lineup, users can choose between fixed-lens models and versions with a dual 20 mm/60 mm field of view, allowing the series to cover everything from wider-area scanning to more deliberate target identification and shot preparation. That makes the Ares 2.0 family relevant for hunting optics users who move between woodland, open ground, and mixed terrain rather than staying in one fixed style of shooting.

About the ThermTec Ares 660L 2.0

The ThermTec Ares 660L 2.0 is the dual-field-of-view, rangefinding model in the series, built for users who need one thermal rifle scope to cover both searching and precise engagement. Its defining feature is the 20 mm/60 mm F1.0 objective system, which gives a wide 1.1x view for fast scanning and then shifts to 3.2x optical magnification when more detail and a narrower aiming picture are needed. In practice, that means less compromise between situational awareness and target assessment, especially in varied hunting terrain.

The thermal core uses a 640x512 VOx sensor with 12.00 μm pixel pitch, 20.00 mK sensitivity, and a 50.00 Hz refresh rate. Together, these features help the image stay fluid while preserving fine thermal contrast, which matters when animals are partly obscured by vegetation or when background temperatures are close to the target. The 2600.00 m detection range extends the scope’s usefulness for observation well beyond normal shooting distances.

This model also integrates a 1000.00 m laser rangefinder with +/- 1 m accuracy and ballistic software, so distance measurement and aiming correction are handled within the same sight picture. The AMOLED 1024×768 display supports clear viewing, while seven reticles with illumination let the user tailor the aiming image to different backgrounds and preferences. Recording functions, WiFi connectivity, and a 12.00 h battery life add practical value for longer sessions, reviewing footage, and managing the device in the field.

About ThermTec

ThermTec Technology Co., Ltd. was established in 2011 and is based in Hangzhou, Zhejiang, China. The company focuses on infrared thermal-imaging systems and solutions, with in-house expertise spanning optics design, detector production, and AI-driven calibration. That background is directly relevant to products such as thermal rifle scopes, where image processing, sensor integration, and optical design all have to work together in changing outdoor conditions.

ThermTec’s outdoor range includes thermal monoculars, imaging sights, clip-on devices, and multispectrum binoculars. Across these categories, the brand is known for using its NST algorithms and other proprietary image-processing technologies to improve image consistency and usability. In the thermal hunting optics segment, ThermTec’s focus is on practical field performance: stable imaging, compact form factors, and feature sets that combine observation, ranging, and recording in one device.
