iRay USA ZOOM Monocular 1x/2x19/38mm - ZH38

Undoubtedly, the zoom dual field of view monocular stands as the most technologically advanced handheld thermal optic to ever emerge in the market's history. This assertion may sound audacious, but any attempt to describe the zoom falls short of its remarkable capabilities. What sets it apart the zoom embodies three pivotal technological advancements: adjustable optical zoom, shutterless calibration technology (SCT) and a vibrant full color 1440x1080 OLED display. While the zoom ZH38 possesses several remarkable attributes, it is the adjustable optical zoom feature that truly propels the zoom ZH38 into a league of its own. Through the innovative patented dual-field-of-view design of the zoom, users seamlessly transition between a wide field-of-view (FOV) optimized for detection and a narrow FOV ideal for target identification. This optical magnification advancement of 2X is easily achieved with an intuitive twist of the objective focus ring, preserving 100 percent of the sensor's native resolution. Why is adjustable optical zoom a game-changer Historically, thermal monoculars featured a fixed field of view, necessitating digital zoom adjustments through software. Unfortunately, digital zoom compromises thermal image resolution. A mere step of digital zoom on a 640x480 sensor diminishes the thermal image resolution to 320x240 and further digital zoom steps lead to a dismal 160x120 resolution. The zoom ZH38 revolutionizes this challenge through its adjustable optical zoom feature. A single device now offers an adaptable field of view. A twist of the focus ring to the right results in a 1X - 640x512 thermal resolution image, while a twist to the left provides a 2x - 640x512 thermal resolution image. The fixed field of view limitation that thermal monoculars have long grappled with, resulting in image degradation via digital zoom and the need for dual devices to attain dual fields of view in full resolution, has been a persistent issue. Infiray outdoor meticulously addressed this common challenge, dedicating resources to years of research and development to find a solution. The culmination of this endeavor is the innovative patented dual field of view lens design, now presented for the first time in the commercial market through the zoom ZH38 dual field of view Monocular.
