REED R2050 Lens
The Thermal Imager has a lens. FOV is the largest area that your imager can see at a set distance. This table lists the horizontal FOV, vertical FOV and IFOV for lens. Focal Length: 9mm Horizontal FOV: 17° IFOV: 3.78mrad Vertical FOV: 17° IFOV (Instantaneous Field of View) is the smallest detail within the FOV that can be detected or seen at a set distance, the unit is rad. The formula is: IFOV = ( Pixel Size )/ ( Lens focal length ); D:S theoretical ( = 1/ IFOV theoretical) is the calculated spot size based on the pixel size of the Thermal Imager detector array and lens focal length. Example: If Thermal Imager uses 9mm lens, because the pixel size of detector is 34um. Horizontal FOV is 17°, Vertical FOV is 17°, the IFOV is 34um/9mm = 3.78mrad;
