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. |
