Lens and imager Field of View

This table lists the horizontal FOV, vertical FOV and IFOV for lens.
Focal Length Horizontal FOV Vertical FOV IFOV
7 .5mm   21 °    21 °     4.53mrad
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 this:

• 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/7.5mm = 4.53mrad;

D:S theoretical [ = 1/IFOV theoretical] = 220:1
D:S measure = D:S theoretical/3 = 74:1

• D:S measure[= 1/IFOV measure] is the spot size needed to provide an accurate temperature measure.
• Typically D:Smeasure is 2 to 3 times smaller than D:S theoretical, which means the temperature measurement area of the target need to be 2 to 3 times larger than that determined by the calculated theoretical D:S.
