Dali S750 Thermal Binocular

• 384x288 thermal sensor: The uncooled FPA sensor gives the Dali S750 enough detail for reliable target detection and general observation, while the 50 Hz refresh rate keeps movement looking smooth when scanning terrain or tracking animals.
• 2x to 4x viewing range: A native 2.00 x view offers a broad image for searching, and the extended magnification helps inspect heat signatures more closely without changing devices in the field.
• OLED 800x600 display: The OLED screen delivers clear contrast and a crisp image presentation, which helps separate warm targets from background clutter and reduces viewing fatigue during longer sessions.
• Dual-eye binocular format: With separate focusing and diopter adjustment on both eyepieces, the S750 is easier to tailor to the user and more comfortable for prolonged observation than many single-eye thermal devices.
• Recording-ready, weather-resistant housing: Built-in photo and video capture, video output, waterproof and fogproof construction, and a 5.00 h battery life make the unit practical for field documentation in changing conditions.

About the Dali S Series

The Dali S Series is DALI's thermal binocular family for users who need a dedicated observation device rather than a weapon sight. In this range, the emphasis is on dual-eye viewing, integrated recording functions, and a layout suited to extended surveillance, wildlife observation, and general thermal scanning. The series includes the S750 and S763 lines, with variants that differ in sensor format, display configuration, and whether a laser rangefinder is included.

A defining trait of the series is its use of uncooled thermal detectors operating in the 8–14 μm spectral range, paired with OLED displays for clear thermal image presentation. DALI positions the S Series as a practical outdoor platform, combining thermal observation with visible-light imaging and onboard photo and video recording. Across the family, the design focuses on field durability, with IP67 protection and a housing intended for use in demanding weather and rough terrain. That makes the S Series a sensible fit for professional observation, patrol work, search tasks, and other situations where thermal awareness matters more than compact pocket size.

About the Dali S750 Thermal Binocular

The Dali S750 Thermal Binocular is the standard-resolution model in the S family, built around a 384x288 uncooled FPA sensor and a 50.00 mm objective lens. This configuration is well suited to users who need dependable thermal detection and observation at medium to longer distances while keeping the image scale manageable for scanning broader areas. Its 2.00 x base magnification gives a useful starting view for searching, while the extended 4.00 x setting helps examine heat sources in more detail when a closer look is needed.

The thermal image is shown on an 800x600 OLED display, which provides the contrast and clarity needed for practical field use in low light, darkness, haze, or visually cluttered backgrounds. A NETD of 60.00 mK supports usable thermal separation in typical outdoor conditions, and the 50.00 Hz refresh rate helps maintain a fluid image when panning or following moving subjects. The binocular layout also matters: separate focus for each eye and diopter adjustment on both eyepieces allow the device to be tuned to the user more precisely, improving comfort during longer observation sessions.

For field documentation, the S750 supports image capture, video recording, and video output, so it can record observations as they happen. Its 1400.00 g body, waterproof and fogproof construction, and operating range of - 30°C / + 50°C make it suitable for outdoor use where weather, temperature shifts, and long periods of handheld observation are part of the job.

About Dali

DALI traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. The company was restructured in 2001 and listed on the Shenzhen Stock Exchange in February 2008. Based in Hangzhou, Zhejiang, China, DALI focuses on infrared and optoelectronic technologies, with work spanning thermal-imaging systems, infrared core components, optoelectronic inertial-navigation products, and more complex integrated optoelectronic systems.

In the thermal sector, DALI is particularly associated with uncooled focal-plane-array detectors and infrared imaging systems, which are directly relevant to handheld and observation devices such as thermal binoculars. Its professional thermal-imaging brand IRtech identifies itself as originating from DALI. The company’s outdoor range includes thermal monoculars, riflescopes, and binoculars, reflecting a product focus on practical field observation tools rather than general consumer electronics.
