Infiray ZOOM ZH50 Thermal Monocular


Infiray Zoom ZH50 is a high-end thermal imaging monocular for outdoor. It has greater magnification and keeps three unique technologies of ZOOM series: Dual Field of View, 1440×1080 HD Resolution and Shutterless Calibration Technology. With the ZOOM’s patented dual-field-of-view design, observers can seamlessly switch between a wide field-of-view (FOV) for detection, and a narrow FOV for target identification. It could be extensively used for night hunting, observation and terrain positioning, search, rescue, and more.

Infiray ZOOM ZH50 

ZOOM’s Three Unique Techs

Dual Field of View Design

The wider FOV with a focal length of 25mm can be used for target search while the narrower FOV with a focal length of 50mm can be used for target identification.

Dual Field of View Design

The detection distance can reach up to 2.6km and with F-number 0.88/1.1, imaging clarity can be lifted to a new level.

Dual FOV Example

1440×1080 FHD OLED Display

The 1440×1080 FHD OLED display is excellent when used for. The 20×magnification eyepiece makes the target search more accurate and the observation distance is longer.

FHD OLED Display

Shutterless Technology

The shutterless core module is adopted to nullify the shutter calibration, simplify the operation.

12µm Thermal Imaging Sensor with NETD ≤25mK

The ZH50 is equipped with an uncooled VOx 12um 640×512 high resolution sensor featuring NETD ≤25mk (25°C, F#=1.0). With the powerful sensor and image algorithm a better image quality is provided. Even in heavy fog and rain, the built-in ultra clear mode can also result in clear imaging through a more detailed field of view and enhanced object identification capabilities.
