Dali RS2 25-240 Thermal Rifle Scope

• 10x fixed magnification: The fixed-power layout keeps the sight picture consistent, which helps when the rifle is set up for a defined shooting distance and repeatable target observation.
• 240x180 uncooled thermal sensor: The thermal core detects heat rather than visible light, allowing the scope to remain usable in darkness, haze, and visually cluttered backgrounds where conventional optics lose contrast.
• 50 Hz refresh rate: A faster refresh rate makes panning and tracking look smoother, which is especially useful when following moving game or scanning across uneven terrain.
• AMOLED display with photo and video recording: The AMOLED screen presents the thermal image with clear contrast, while built-in image capture and video recording let the user document sightings and review shots afterward.
• WiFi and USB-C power interface: Wireless connectivity adds convenient image sharing and app-based viewing, while USB-C charging and the rechargeable battery simplify field power management.

About the Dali RS Series

The Dali RS series is DALI’s family of dedicated thermal rifle scopes for hunters and other users who need a purpose-built aiming optic rather than a handheld viewer adapted to rifle use. Within the brand’s outdoor thermal range, the series focuses on combining a riflescope-style format with core thermal functions such as uncooled focal-plane-array sensors, onboard recording, and wireless connectivity. The design emphasis is practical field use: a compact housing, rechargeable power system, and straightforward controls suited to observation and shot placement in low light or complete darkness.

Across the series, DALI pairs thermal imaging with features that matter in real use, including WiFi connectivity, built-in storage for captured media, and a USB-C interface for charging and data transfer. The platform is built around 17 μm detector technology and a 50 Hz refresh rate, giving the series a balance of image responsiveness and manageable size. Depending on model, the RS line covers different detector resolutions and lens configurations, so users can choose between wider-area scanning or more detail at distance while staying within the same general operating concept.

About the Dali RS2 25-240 Thermal Rifle Scope

The Dali RS2 25-240 Thermal Rifle Scope is a compact thermal aiming optic built around a 240x180 sensor with 17.00 μm pixel pitch and a 25.00 mm objective lens. This configuration suits users who want a straightforward thermal riflescope for short- to mid-range detection and target observation, where the priority is seeing heat signatures clearly rather than relying on ambient light. Because thermal imaging separates warm targets from cooler surroundings, the scope remains effective in darkness and in conditions where shadows, brush, or background contrast make conventional optics harder to use.

The fixed 10.00 x magnification gives the RS2 a stable viewing scale that can work well on rifles set up for a known role, avoiding the extra control inputs of a variable-power system. Its 50.00 Hz refresh rate helps the image stay smoother during panning and target tracking, while the 60.00 mK NETD supports thermal contrast that is useful for distinguishing animals or other heat sources from the background. The AMOLED display provides a bright, high-contrast viewing surface, which is important in a thermal optic because display quality directly affects how easily small temperature differences can be interpreted in the field.

For practical use away from the bench, the scope combines photo capture and video recording with WiFi connectivity, making it easier to save observations or share footage. A rechargeable battery with 5.00 h of stated life, plus USB-C charging support, keeps power management simple. The waterproof and fogproof construction, 700.00 g weight, and 250.00 mm overall length make it a field-ready thermal riflescope that stays relatively compact on the rifle.

About Dali

DALI traces its roots to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. The company is based in Hangzhou, Zhejiang, China, and was restructured in 2001 before being listed on the Shenzhen Stock Exchange in February 2008. In the thermal-imaging market, IRtech identifies itself as originating from DALI, linking the outdoor product line to the company’s broader infrared and optoelectronic background.

DALI’s expertise centers on infrared core components, thermal-imaging systems, optoelectronic inertial-navigation products, and other complex optoelectronic systems. For products such as thermal rifle scopes, the most relevant part of that background is its work with uncooled focal-plane-array detectors and infrared thermal-imaging cameras and systems. Its outdoor range includes thermal monoculars, riflescopes, and binoculars, showing a clear focus on applying that detector and imaging experience to field observation and weapon-mounted thermal optics.
