IRay Zoom ZH38 – Thermal Monocular
The IRay Zoom ZH38 is the first of its kind as a Dual Field of View Thermal Monocular in the commercial market. Allowing for seamless switching between a wide field of view for detection and a narrow field of view for identification. The dual field of view monocular is the most technologically advanced thermal handheld on the market. There are 3 specific leaps in technology: adjustable optical zoom, shutterless calibration technology (SCT), and a full color 1440×1080 OLED display. These aren’t the only impressive features the ZOOM ZH38 has to offer, but these three and most importantly the adjustable optical zoom feature are what puts the Zoom in its own league.
With the ZOOM’s patented dual field of view design, users can seamlessly switch between a wide field of view (FOV) for detection, and a narrow FOV for target identification. This 2X increase in optical magnification occurs with an intuitive twist of the objective focus ring and maintains 100% of the sensor’s native resolution.
Why is adjustable optical zoom so important? Thermal monoculars have historically only been offered with a fixed field of view, which means the only way to zoom in and out is digitally through software and digital zoom decreases thermal image resolution. Just 1 step of digital zoom on a 640×480 sensor degrades the thermal image resolution to 320×240, and another step of digital zoom degrades the thermal image resolution to an abysmal 160×120. This is the problem that is solved by the ZOOM ZH38’s adjustable optical zoom feature. You now have 1 device with an adjustable field of view. Twist the focus ring to the right to zoom out and you get a 1X – 640×480 thermal resolution image, twist it to the left and get a 2X – 640×480 thermal resolution image.
