Dali RS135-640 Thermal Rifle Scopes

• 640x480 thermal sensor: The higher detector resolution gives the Dali RS135-640 a more detailed thermal image, which helps separate animals, terrain features, and background heat at longer distances.
• 35 mm objective with 2300.00 m detection range: This configuration balances reach and field coverage, making the scope suitable for scanning open ground while still retaining enough detail for target recognition.
• 1280x960 OLED display: The high-resolution OLED screen presents a crisp viewing image with strong contrast, reducing the coarse look that can make prolonged thermal observation tiring.
• 50.00 Hz refresh rate: A faster refresh rate keeps motion looking smoother when tracking moving game or panning across a field, so the image remains easier to interpret in real time.
• WiFi, photo capture, and video recording: Built-in connectivity and recording functions let the scope document observations and share footage without adding external accessories.

About the Dali RS Series

The Dali RS series is DALI’s thermal riflescope family for users who need a dedicated sighting system rather than a general-purpose handheld thermal device. In the lineup, the series is built around a practical hunting and field-use format, combining a riflescope-style housing with thermal imaging functions such as uncooled focal-plane-array detectors, onboard recording, and wireless connectivity. The series includes versions with 384×288 or 640×480 detectors and either 35 mm or 50 mm lenses, allowing the range to cover different balances of field of view and detection reach.

Across the family, the design focuses on straightforward operation in low-light and no-light conditions. RS models use 17 μm pixel pitch sensors with a 50 Hz frame rate, rechargeable battery power, and a USB-C interface for charging and data transfer. WiFi, built-in storage, and photo and video recording are part of the concept, so the scope works not only as an aiming optic but also as an observation and documentation tool. The series also supports multiple viewing palettes, digital zoom steps, and hotspot tracking, giving users a thermal riflescope platform suited to night hunting, pest control, and general thermal observation.

About the Dali RS135-640 Thermal Rifle Scopes

The Dali RS135-640 Thermal Rifle Scopes is the higher-resolution 35 mm model in this configuration, pairing a 640x480 uncooled FPA sensor with a 10.00 x optical magnification. That combination is aimed at users who prioritize image detail and target discrimination, especially when scanning at distance or working in cluttered thermal backgrounds where lower-resolution devices can merge shapes together. The 2300.00 m detection range gives the scope enough reach for wide-area observation, while the 17.70 ° field of view remains broad enough to help with locating heat signatures efficiently.

The viewing experience is shaped by the 1280x960 OLED display, which gives the thermal image a cleaner and more contrast-rich presentation than lower-resolution screens. In practice, this makes prolonged observation easier and helps the user judge edges, movement, and separation between target and background more confidently. The 50.00 Hz refresh rate also matters in real use, because it keeps panning and target movement smoother when following animals or checking multiple sectors quickly.

For field use, the scope combines thermal imaging with practical digital functions. Photo capture and video recording allow observations to be saved directly from the optic, while WiFi connectivity adds a simple way to transfer or review material. The rechargeable battery system supports 7.00 h of operation, and USB-C power adds convenience for charging in camp, in a vehicle, or from a power bank. With waterproof and fogproof construction and an operating range of -20℃~50℃, this Dali thermal riflescope is built for regular outdoor use in changing weather.

About Dali

DALI traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. Based in Hangzhou, Zhejiang, China, the company developed from a research background into a manufacturer focused on infrared and optoelectronic systems. It was restructured in 2001 and listed on the Shenzhen Stock Exchange in February 2008.

In this product category, DALI is known for work in uncooled focal-plane-array detectors, infrared thermal-imaging cameras, and complete thermal-imaging systems. Its product scope also includes infrared core components, optoelectronic inertial-navigation products, and more complex integrated optoelectronic systems. The company’s outdoor thermal range covers riflescopes, monoculars, and binoculars, while IRtech is presented as a professional thermal-imaging brand originating from DALI. That background is directly relevant to the RS series, which draws on the company’s detector and thermal-system expertise rather than adapting a conventional day optic design.
