Thermal Imaging Scopes

Sensor resolution: The number of pixels used by the sensor. The more pixels, the more detail in the image. A high resolution is recommended for observing distant or small animals.

Pixel pitch (µm): The distance between the pixels on the sensor. A smaller pixel pitch results in higher magnification and more detail. A larger pixel pitch, on the other hand, offers better thermal sensitivity, especially under challenging conditions.

Thermal sensitivity / NETD: Noise Equivalent Temperature Difference. This value indicates how well the camera can distinguish small temperature differences. The lower the NETD value, the more sensitive and better the image.

Field of View (FOV): The size of the area you see in the image. This is usually expressed in degrees or meters at a distance of 100 meters. With a wide field of view, you see more of the surroundings in a single image. However, a larger field of view comes at the expense of magnification: the wider the FOV, the lower the magnification and the less distance you can see.
