Dali RS150-640 Thermal Rifle Scope

• 640x480 thermal sensor: The higher-resolution detector gives this thermal riflescope a cleaner view of animals, heat sources, and background detail, which helps with target recognition at longer distances and in cluttered terrain.
• 50 mm objective lens: A larger front lens collects more thermal information, supporting the scope’s 3300.00 m detection capability and making distant heat signatures easier to pick up.
• OLED 1280x960 display: The high-resolution OLED screen presents the thermal image with strong contrast and a crisp sight picture, reducing eye strain during longer observation sessions.
• 50.00 Hz refresh rate: Fast image refresh keeps movement looking smoother when scanning or tracking game, which is especially useful when targets are moving across the field of view.
• Wi-Fi, photo and video recording: Built-in connectivity and recording let the scope document observations and share footage without extra accessories, which is useful for review, training, or field reporting.

About the Dali RS Series

The Dali RS series is DALI’s thermal riflescope family built around uncooled focal-plane-array detectors and a practical feature set for field use after dark. Within the brand’s outdoor thermal lineup, the series is aimed at users who need a dedicated thermal sight for hunting, observation, and general night-time target detection rather than a simple clip-on or handheld viewer. A defining characteristic of the range is its use of 17 μm pixel pitch sensors paired with a 50 Hz frame rate, giving the image a stable, fluid look when scanning ground or following movement.

Across the series, DALI combines thermal imaging essentials with useful digital functions instead of overcomplicating the interface. Typical RS models support black-hot and white-hot palettes, hotspot tracking, and multiple digital zoom steps, while also integrating Wi-Fi, built-in photo and video recording, and 32 GB of internal storage. USB-C charging and data transfer, rechargeable battery power, and operating time exceeding 7 hours make the series suitable for longer outings. The lineup covers both 384x288 and 640x480 detector options with 35 mm or 50 mm lenses, allowing users to choose between wider coverage or more reach depending on the terrain and expected engagement distance.

About the Dali RS150-640 Thermal Rifle Scope

The Dali RS150-640 Thermal Rifle Scope is the higher-detail, longer-reach configuration within this format, combining a 640x480 thermal sensor with a 50.00 mm objective lens and fixed 10.00 x magnification. That combination suits users who prioritize target identification and observation at distance over a wide, low-power view. The scope’s stated 3300.00 m detection range reflects that emphasis: it is built to pick up heat sources far beyond normal shooting distances, giving the user more time to assess movement and terrain before taking action.

The thermal core uses an uncooled FPA sensor with 17.00 μm pixel pitch and 60.00 mK NETD. In practical terms, this means the scope is designed to separate useful heat signatures from the background with enough clarity for field work in changing weather and uneven thermal conditions. The 50.00 Hz refresh rate helps preserve a natural-looking image when panning across open ground or following moving animals, while the OLED 1280x960 display gives the image strong contrast and a defined viewing window.

For field usability, the scope adds Wi-Fi connectivity, thermal image capture, and video recording, so observations can be saved directly from the device. A rechargeable battery system with 7.00 h battery life and USB-C power support keeps the platform practical for extended sessions. Waterproof and fogproof construction further suits the RS150-640 to hunting optics use in cold mornings, damp vegetation, and variable outdoor conditions.

About Dali

DALI traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. The company is based in Hangzhou, Zhejiang, China, and it was restructured in 2001 before being listed on the Shenzhen Stock Exchange in February 2008. In the thermal-imaging field, DALI focuses on infrared core components, thermal-imaging systems, optoelectronic inertial-navigation products, and other complex optoelectronic systems.

A key part of the company’s expertise is its work with uncooled focal-plane-array detectors and infrared thermal-imaging cameras and systems, which is directly relevant to products such as thermal riflescopes and observation devices. IRtech identifies itself as a professional thermal-imaging brand originating from DALI, and the company’s outdoor range includes thermal monoculars, binoculars, and riflescopes. That background places DALI as a specialist manufacturer with in-house experience in the sensor and imaging technologies that define this category.
