Dali S750MH Thermal Binocular

• 384x288 thermal sensor: The uncooled FPA sensor gives this thermal binocular enough detail for reliable target detection and observation while keeping the system practical for field use.
• OLED 800x600 display: A high-resolution OLED screen delivers strong contrast and clear image presentation, which helps when scanning terrain, identifying heat sources, and observing for longer periods.
• 2x to 4x viewing range: The base 2.00 x magnification offers a useful overview for searching, while the higher digital zoom setting helps inspect distant details without changing position.
• Binocular viewing design: With separated focusing for each eye and diopter adjustment on both eyepieces, the S750MH is easier to tailor to the user and more comfortable during extended observation sessions.
• Photo and video recording: Built-in image capture, video recording, and video output make it suitable for documenting observations, reviewing events, or sharing the live view with external equipment.

About the Dali S Series

The Dali S Series sits in DALI’s outdoor thermal binocular range as a family built for users who need a dedicated observation device rather than a compact pocket monocular. Within the series, S750 and S763 models cover different configurations, including versions with and without additional ranging capability, while keeping the same general focus on thermal detection and field observation. The series is designed around uncooled thermal detectors operating in the 8–14 μm spectral range, which is the standard band for passive thermal imaging in outdoor use.

Across the range, DALI pairs thermal imaging with OLED displays and recording functions, giving the S Series a practical role in surveillance, search, wildlife observation, and other low-visibility tasks. The binocular format favors steadier viewing and better long-session comfort than many single-eyepiece devices. The series also emphasizes field durability, with IP67-rated protection and a housing concept intended for demanding environments. Some models in the family add visible-light imaging or a laser rangefinder, so the S Series is positioned as a modular thermal binocular platform for users who need more than simple heat detection.

About the Dali S750MH Thermal Binocular

The Dali S750MH Thermal Binocular is a thermal observation device built for users who need a stable two-eye viewing format, onboard recording, and integrated measurement functions in one housing. Its 384x288 uncooled thermal sensor and ≤60 mK NETD are aimed at practical heat-source detection in difficult light, haze, or mixed terrain, while the 50 Hz refresh rate helps the image remain smooth when scanning or tracking movement. The 41.00 mm objective and 9.00 ° field of view balance area coverage with enough image scale for observation work.

The viewing system combines 2.00 x optical magnification with up to 4.00 x maximum magnification, giving the S750MH a useful spread between wider-area searching and closer inspection of distant heat signatures. Its OLED 800x600 display supports clear contrast and easy interpretation of thermal scenes, which matters when distinguishing animals, people, or vehicles from background clutter. Separate focusing for each eye and diopter adjustment on both eyepieces make the binocular easier to adapt to individual eyesight and more comfortable over long sessions.

This model also stands out for its broader field functionality. It supports photo capture, video recording, and video output, so observations can be documented or shared externally. The S750MH variant adds GPS, an electronic compass, and a built-in laser rangefinder, which makes it more suitable for coordinated observation and distance assessment than a basic thermal viewer. With waterproof and fogproof construction, a 5.00 h battery life, and operation from - 30°C / + 50°C, it is configured for demanding outdoor use.

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 deep expertise in infrared technology and later expanded into a broader optoelectronics business. It was restructured in 2001 and listed on the Shenzhen Stock Exchange in February 2008.

In the thermal-imaging field, DALI is known for work on uncooled focal-plane-array detectors, infrared thermal-imaging cameras, and complete imaging systems. Its product development also covers infrared core components, optoelectronic inertial-navigation products, and more complex optoelectronic systems. The company’s outdoor thermal range includes monoculars, riflescopes, and binoculars, while IRtech is presented as a professional thermal-imaging brand originating from DALI. That background is directly relevant to products like the S750MH, which combine detector technology, field-ready housing, and observation-oriented system design.
