ZOOM
The ZOOM Dual Field of View Monocular is unequivocally the most technologically advanced handheld thermal optic to hit the market in history. That’s a bold statement but saying anything else about the ZOOM would be an understatement. What makes it so advanced? There are 3 specific leaps in technology: adjustable optical zoom, Shutterless Calibration Technology (SCT), and a full color 1440x1080 OLED display. These aren’t the only impressive features the ZOOM possesses but these three and most importantly the adjustable optical zoom feature are what puts the ZOOM in a league of its own.
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 640x480 sensor degrades the thermal image resolution to 320x240, and another step of digital zoom degrades the thermal image resolution to an abysmal 160x120. This is the problem that is solved by the ZOOM 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 wide field-of-view - 640x480 thermal resolution image, twist it to the left and get a narrow field-of-view - 640x480 thermal resolution image.
