InfiRay Outdoor ZOOM ZH50 640 25MM-50MM Thermal Monocular

Discover unparalleled thermal imaging with the InfiRay Outdoor ZOOM ZH50 640 25MM-50MM Thermal Monocular. This device features adjustable optical zoom, Shutterless Calibration Technology, and a full-color 1440x1080 OLED display, offering crystal-clear imaging. With sophisticated features, this monocular is in a class of its own.

Experience unsurpassed thermal imaging with the InfiRay Outdoor ZOOM ZH50 Thermal Monocular. Its patented dual-field-of-view design allows you to switch between a wide 25mm FOV and a narrow 50mm FOV seamlessly, with an intuitive twist of the objective focus ring, which maintains 100% of the native resolution. Enjoy superior thermal imaging performance.

Adjustable optical zoom is an important feature, as it helps avoid the degraded image resolution of traditional thermal monoculars. Without adjustable optical zoom, users have to rely on digital zoom, which decreases the sensor resolution. For example, 1 step of digital zoom on a 640x480 sensor decreases the thermal image resolution to 320x240, and another step of digital zoom reduces the resolution to an unsatisfactory 160x120. The ZOOM ZH50 offers a solution - with an adjustable field of view. By rotating the focus ring, users can zoom out for a 2X 640x512 resolution image, or zoom in for a 4X 640x512 resolution image.

InfiRay Outdoor discovered the common issue of image degradation caused by fixed field of view limitation in thermal monoculars with digital zoom and the requirement of two devices for dual fields of view in full resolution. Subsequently, significant resources have been allocated for years of research and development, resulting in ZOOM ZH50 Dual Field of View Monocular, the first commercially available, patented dual field of view lens design.
