ThermTec Vidar 660L 2.0

• Dual field of view lens: The 20 mm / 60 mm optical system lets the sight switch between a wide scanning view and a tighter observation view, so it works both for locating heat signatures quickly and for checking detail before the shot.
• 640x512 thermal sensor with 12 μm pixels: This sensor format gives the ThermTec Vidar 660L 2.0 the resolution needed to separate animals from background clutter at longer distances and to preserve useful detail when conditions are difficult.
• Integrated 1200 m laser rangefinder with ballistic support: Built-in ranging and ballistic calculation reduce guesswork in the field, helping the shooter make faster hold decisions without adding a separate rangefinding device.
• AMOLED display and 50 Hz refresh rate: The 1024×768 AMOLED screen presents a clear viewing image, while the 50 Hz refresh rate keeps movement looking smooth when tracking game or scanning across uneven terrain.
• 16-hour power system with 18650 battery: Long runtime supports extended hunting sessions, and the common 18650 format makes power management more practical than relying on a proprietary battery alone.

About the ThermTec Vidar Series

The ThermTec Vidar series was introduced as a line of thermal riflescopes for hunting, aimed at users who need a compact sight with practical field features rather than a bulky specialist unit. Within ThermTec’s thermal sight range, the series combines core hunting functions such as onboard recording, straightforward controls, and model variations tailored to different needs. From the start, the family included both standard and LRF variants, with the laser-rangefinder models adding ballistic calculation for shooters who want ranging and hold support in one device.

A defining trait of the series is its variation in detector and lens configuration across the range, including dual-field-of-view models that can shift between broader situational awareness and more concentrated target observation. The original series specifications also paired 12 μm thermal detectors with 1024 × 768 AMOLED displays, a combination chosen to balance image detail, viewing comfort, and responsive operation in low-light and night-time hunting conditions. Overall, the Vidar concept focuses on practical thermal imaging performance, integrated hunting tools, and a form factor that remains manageable on a rifle.

About the ThermTec Vidar 660L 2.0

The ThermTec Vidar 660L 2.0 is built for hunters who want one thermal riflescope to cover both searching and shot placement. Its standout feature is the dual field of view 20 mm / 60 mm lens system, which gives the sight two distinct working modes. At the wider setting, the image covers more ground and makes it easier to scan woodland edges, fields, or broken terrain for movement and heat sources. At the narrower setting, the sight moves to 3.2x optical magnification, giving a more concentrated image for target assessment and more deliberate aiming.

Thermal performance is centered on a 640x512 VOx uncooled sensor with 12.00 μm pixel pitch and 25.00 mK sensitivity, supported by a detection range of 3000.00 m. In practice, that means the scope is designed not just to detect heat at distance, but also to maintain useful separation between target and background when temperature contrast is limited. The 1024×768 AMOLED display helps present that information with good perceived contrast, while the 50.00 Hz refresh rate keeps panning and target movement looking natural.

The integrated 1200.00 m laser rangefinder and ballistic software make this LRF thermal riflescope especially useful where distance changes quickly and visual estimation is unreliable. With seven reticle options, onboard image capture and video recording, WiFi connectivity, and up to 16.00 h battery life from an 18650 power supply, the Vidar 660L 2.0 is configured for extended night hunting with fewer add-ons and less interruption in the field.

About ThermTec

ThermTec Technology Co., Ltd. was established in 2011 and is based in Hangzhou, Zhejiang, China. The company develops and manufactures infrared thermal-imaging systems and solutions, with a product range that includes thermal monoculars, imaging sights, clip-on devices, and multispectrum binoculars. That focus makes ThermTec a specialist manufacturer in the thermal and night observation segment rather than a general sporting-optics brand.

Its technical work spans optics design, detector production, and AI-driven calibration, which is directly relevant to products such as thermal riflescopes where image consistency and target definition matter in changing conditions. ThermTec also states that it uses proprietary NST algorithms and patented image-processing technologies, reflecting an emphasis on the digital side of thermal imaging as well as the hardware itself. In practical terms, the brand is known for integrating thermal sensors, onboard recording, rangefinding, and app-based connectivity into field-oriented hunting optics.
