Dual Field of View Thermal Monocular

The InfiRay ZOOM ZH38 is a dual FOV handheld thermal imager. It is also features Shutterless Calibration Technology (SCT), simplifying use and reduce power consumption.

iRay Zoom Dual-Field-of-View Comparison

With the ZOOM ZH38'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. A simple, intuitive twist of the objective focus ring doubles the optical magnification while also maintaining 100 percent of the sensor’s native resolution. Digital zoom can’t do that.

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, but zooming in also decreases thermal image resolution. Just one step of digital zoom on a 640x480 sensor degrades the thermal image resolution to 320x240, and the next step degrades it further to an abysmal 160x120.

Previously, the only way to have dual fields of view at full resolution has been to use two devices. The ZOOM ZH38's adjustable optical zoom feature solves the problem. Twist the focus ring to the right to zoom out and you get a 2X thermal image at 640x480 resolution; twist it to the left and you get a 4X thermal image still at 640x480 resolution!

Additionally, the ZOOM ZH38 monocular features a full-color 1440x1080 HD OLED display, working in tandem with its ultra-sensitive 12 µm 640x512 sensor and MATRIX III processing to create a remarkably flexible and eye-popping viewing experience. The detection range is an impressive 2150 yards.

Other features include: 50 Hz frame rate for smooth motion, stepped 4X digital zoom, five imaging modes, picture-in-picture, stadiametric rangefinder, 10 hour battery life, video/image recording, wireless connectivity (via app), and a 5 year warranty.
