Overlay
A DXF file can be laid over the on-screen image for applications which might require a template or guides, such as
comparing machined parts to templates for accuracy. Compatible vector types include line segments, polylines, circles,
ellipses, and text. The graphics cannot exceed 3840x2160 units in order to fit the on-screen display.
Auto Focus
The camera uses a mechanical focus drive which can reposition the image-sensor auto
-
matically or through manual adjustment. This allows the camera to adjust focus inter
-
nally. The drive has a 16mm total range of motion which is displayed on the Auto Focus
control panel. 0mm represents a neutral position based on the standard flange-focal
distance for C-Mount lenses. 10.6mm represents the maximum distance the sensor can
be moved away from the C-Mount interface, and -5.4mm represents movement toward
the C-Mount interface.
When Auto Focus is selected, the focal point will be adjusted automatically and con
-
tinuously. When Manual Focus is selected, you can use the slider to manually adjust
the focal point. While in Manual Focus mode, clicking on the One Push AF button will
temporarily enable the auto-focus until the image is focused, at which point control will
return to the manual mode. The Conj. Cal. button (conjugate calibrate) will return the
focal point to the neutral position.
