4.5 Eyepiece
Focus
The eyepiece can be focused by rotating the eyepiece barrel as shown in
Figure 6. The nominal adjustment range is +2.75 to -1.35 diopters. Unlike
lens focus, which might be varied during operation depending upon whether
you are imaging distant or nearby targets, the eyepiece focus should only
have to be adjusted once for your particular vision. It is recommended that
you adjust the eyepiece focus while viewing the crosshair (or the menu)
rather than objects in the infrared scene, which may be out of focus
depending upon the focus-adjustment of the lens. The seal on the eyepiece
can be tight so it may be necessary to squeeze the base firmly to adjust
focus.
4.6 Lens
Focus
The camera lens is focused by rotating the lens barrel. The nominal focus
range of the 30mm lens configuration is from 1 meter (40 inches) to infinity.
The nominal focus range of the 50mm lens configuration is from 1.5 meters
(60 inches) to infinity.

Figure 13: FlashSight for Image Download
To complete the data download, simply plug the USB cable to the FlashSight
as shown in Figure 13 and power it on. Windows recognizes the system as a
write-protected file-storage device, and images can then be downloaded by
copy and paste. Note that because it is write-protected, it is not possible to
delete stored images via Windows or to add other files.
