Field of View Terminology


Working Distance: Is the distance between the objective lens and the component when the component is in focus
Field Of View (FOV): Is the viewable area. To fill the 16" (400mm) diameter screen when using a 10x lens, the maximum diameter object projected would be 1.6" (40mm).
Half Field View: Is the maximum size a component can be projected to the
center of the screen before colliding with the lens.
Full Field of View: Is the maximum size a component can be projected over the
full screen before colliding with the lens.
Projected Image: Is how a component is projected onto the screen in relation to  its placement on the workstage.
