marking head components.
Note: FLA370 lenses for FH Flyer heads have a notched mounting ring to provide clearance for 5X
expanders. The 370-mm lens mount is dowel-pinned so it mounts in an orientation that provides
clearance for heads tted with the longer 5X expander.

Lens specications
The nominal (or standard) mark eld for FH Series lenses is a square; however, to accommodate custom-
ers who require a slightly larger marking area at the same working distance, our FH Series lenses provide
an extended rectangular mark area beyond the standard eld specication. In WinMark Pro, the white
center area on the Drawing Canvas denotes the nominal (standard) marking area for the currently installed
focusing lens. The outer border (shaded yellow) indicates the maximum marking eld for that lens. Note
that mark objects placed in the yellow shaded area, especially those objects placed near the corners, may
exhibit a slight degradation in mark quality. Table 5-1 lists nominal and maximum eld sizes, working
distance, focused spot size, and depth of field specifications for all FH Flyer lenses.
Note: See Initial start-up and Figure 3-2 in the Operation chapter for information on setting the correct
working distance for your focusing lens.
