Fluke IR Window eld of view
73.66 cm (29 in)
These Field of View (FOV) calculations are based on best practices used during infrared inspections and serve as a guide when
choosing IR Window sizes and locations.
Please note that the illustrations represent achievable FOV at a distance of 30.48 cm (12 in) to target. Additional FOV
calculations at various distances to target are given in the tables below. Actual FOV can vary based upon equipment layout
(phase barriers, internal compartments, etc.). Be sure to verify IR Window position before drilling holes for installation.
For illustration purposes, only horizontal FOV is shown. Adjusting the position of the thermal imager allows the overall
FOV to be achieved in all directions—360 degrees.
