Microthermo Technology MT4 MINI, 35 mm lens

• 384x288 thermal sensor: This resolution gives the MT4 MINI enough detail for reliable heat-source detection and target recognition while keeping the device compact and light for regular field carry.
• 30.00 mK sensitivity: A low NETD helps the monocular separate small temperature differences, which makes animals, people, and other warm objects stand out more clearly in difficult weather and low-contrast scenes.
• 1.00x to 4.00x magnification: The wide base view supports scanning at close to medium distances, while higher digital magnification helps inspect a detected heat signature without changing position.
• OLED display: An OLED screen provides clear image presentation with strong contrast, helping the user read thermal detail more comfortably during night observation.
• 190.00 g compact housing: With its low weight and 106.00 mm overall length, the MT4 MINI is easy to carry in a pocket or pack and practical as a quick-access handheld thermal monocular.

About the MT4 Series

The Microthermo Technology MT4 series is a family of compact handheld thermal monoculars built for users who need a simple, portable thermal imaging tool for observation, detection, and general field use. Within the manufacturer’s thermal lineup, the MT4 series focuses on small size, low weight, and straightforward operation rather than bulky housings or weapon-mounted formats. That makes it well suited to hunting support, property monitoring, outdoor navigation after dark, and routine surveillance tasks where fast deployment matters.

Across the series, the design centers on an uncooled FPA thermal sensor, a compact optical system, and a high-contrast OLED display. This combination is intended to deliver a clear thermal image in a handheld format that is easy to carry for long periods. The series also emphasizes practical field durability, with waterproof and fogproof construction for use in changing weather. MT4 models are aimed at users who want thermal capability in a light monocular that can be carried as a constant companion rather than a specialist device reserved for occasional use.

About the Microthermo Technology MT4 MINI, 35 mm lens

The Microthermo Technology MT4 MINI, 35 mm lens is a compact thermal monocular designed for handheld observation where low weight and quick access matter as much as image quality. Its 35.00 mm objective lens works with a 384x288 sensor to provide a practical balance between portability and usable thermal detail. For scanning woodland edges, checking fields, or monitoring a property line, the base 1.00x magnification keeps the image natural and easier to interpret, while the upper 4.00x magnification helps examine a detected heat source more closely.

A key strength of this model is its 30.00 mK NETD, which improves the separation of subtle temperature differences. In practice, that helps reveal animals or people more clearly when the thermal contrast in the environment is weak. The 25.00 Hz refresh rate supports smooth enough image updates for routine observation and tracking of movement in the field. The OLED display further helps by presenting thermal information with strong contrast, which is useful during prolonged nighttime viewing.

Mechanically, the MT4 MINI is built for easy carry. At 190.00 g and only 106.00 mm long, it is light enough for a jacket pocket, chest pouch, or pack without becoming a burden. Its AA power supply keeps battery sourcing straightforward, while automatic brightness control helps maintain a usable image in changing viewing conditions. Waterproof and fogproof construction adds reassurance for outdoor use, and the operating range of -10 ºC ... +60 ºC suits the varied conditions typical of hunting and general thermal observation.

About Technologie Microthermo

Hangzhou Microthermo Technology is based in Hangzhou, China and focuses on the development and manufacture of infrared thermal imaging equipment. Its work covers thermal imaging modules, cores, lenses, and cameras, which places the company firmly in the technical side of the thermal optics market rather than only final product assembly. That background is relevant in a handheld thermal monocular because core sensor integration and optical matching have a direct effect on image consistency and usability.

The company’s range includes uncooled, shutterless thermal imaging modules, and its technology is used in applications such as hunting, weapon sights, and surveillance. Within its own monocular lineup, the MT4 sits alongside other thermal product families such as the MTW and W series. This gives the brand a clear specialization in compact infrared observation devices and related thermal imaging components.
