Microthermo Technology W38419

• 384x288 thermal sensor: The sensor delivers enough detail for reliable observation and target recognition at practical field distances, while the 17.00 μm pixel pitch helps keep the device compact and efficient.
• 1.00x to 4.00x magnification: A true 1.00x base view is easier for scanning and situational awareness, while digital magnification up to 4.00x gives extra image scale when checking heat signatures in more detail.
• Shutterless calibration: The shutterless system avoids the brief interruptions associated with traditional calibration cycles, so the image remains more continuous during observation.
• 19.00 mm objective and 470.00 m detection range: This combination gives the monocular useful reach for short- to mid-range thermal spotting, helping the user detect heat sources beyond normal visual range.
• Aluminium housing with waterproof and fogproof construction: The robust body and weather-resistant build are better suited to outdoor use, transport, and changing conditions than a lighter consumer-style housing.

About the Microthermo Technology W Series

The Microthermo Technology W Series is a compact family of handheld thermal devices built around the company’s experience with uncooled, shutterless thermal imaging. Within the brand’s thermal lineup, the W series is aimed at users who need a portable observation tool rather than a large dedicated sighting system. That makes it relevant for field observation, hunting support, general surveillance, and other tasks where fast thermal detection matters more than bulk or high optical magnification.

A defining characteristic of the series is its focus on practical thermal viewing in a small format. Models in this line combine a compact housing with thermal sensors designed for continuous observation, and the use of shutterless calibration supports a more fluid viewing experience. The series is also shaped around straightforward handling, with controls and viewing ergonomics intended for quick deployment in the field. In use, the W series prioritizes the core strengths expected from a handheld thermal monocular: rapid heat-source detection, operation in difficult light conditions, and a durable body suited to outdoor environments.

About the Microthermo Technology W38419

The Microthermo Technology W38419 is a compact thermal monocular built for users who need a lightweight device for scanning terrain, checking tree lines, or locating heat sources without carrying a larger thermal optic. Its 384x288 uncooled FPA sensor gives this model a balanced position between image detail, power consumption, and overall size, making it suitable for practical field observation. With a 19.00 mm objective lens and a stated 470.00 m detection range, it is configured for short- to medium-distance thermal spotting where quick detection is more important than long-range image enlargement.

The magnification system starts at 1.00x, which is useful when scanning because it preserves a more natural view and makes it easier to follow movement. Digital magnification up to 4.00x then allows closer inspection of a detected heat signature, although the main benefit of this model remains fast observation rather than precision identification at extreme distance. The 50.00 Hz refresh rate supports smoother image presentation when panning, and the shutterless calibration design helps maintain continuity during use.

In practical handling, the W38419 is built around a compact 110.00 mm body and a weight of 380.00 g, so it is easy to carry as a thermal companion in the field. The aluminium housing, waterproof and fogproof construction, and operating range of -20 ºC ... +60 ºC support use in varied weather conditions. A central diopter setting, a diopter range of -7 ... +4, and the integrated compass further improve usability during extended observation sessions.

About Technologie Microthermo

Hangzhou Microthermo Technology is based in Hangzhou, China and specializes in thermal imaging hardware rather than general sporting optics. Its work centers on the development and manufacture of infrared thermal imaging modules, cores, lenses, and cameras, which places the company close to the underlying technology used inside finished thermal devices. The product range includes uncooled, shutterless thermal imaging modules, reflecting a focus on compact systems designed for continuous observation.

Microthermo technology is used across applications such as hunting, weapon sights, and surveillance, showing that the company’s products are intended for both field and observation roles. Its handheld thermal lines include the MT4, MTW, and W series, while reported module formats such as 384×288 and 640×480 indicate coverage of both compact and higher-resolution thermal platforms.
