Field of View -- Distance vs. Spot Diameter. An IR thermometer's field-of-view (FOV) is a critical property to be aware of. It determines the relationship between the distance from an object and the area of space being observed. The MLX90614's field of view is cone-shaped -- its sensing area is very narrow if it's near the object, but gets increasingly wider as it moves farther away. The ...
