Lens used

The GO-5000-USB employs a 1-inch CMOS imager. It is necessary to select a 1-inch C mount lens if
the full resolution of the camera is to be utilized. The imager used in the GO-5000-USB measures
16.392 mm diagonally, which is slightly larger than the standard 16 mm diagonal of the 1-inch
format. Please consult with your lens provider to select a 1-inch lens able to cover 16.392 mm
diagonally, otherwise the image captured may show vignetting.
It is possible to use C mount lenses with an optical format smaller than 1-inch, provided a less-than
full-resolution ROI is going to be used. For example, a centered ROI of 1920 x 1080 pixels (HD
format) will fit inside the image circle of most standard 2/3-inch C mount lenses. Likewise, a
centered VGA ROI (640 x 480 pixels) can be accommodated by a standard 1/3-inch C mount lens.
The rear protrusion on any lens used must be less than 10 mm.
The focal length of lens used is estimated by the following formula.
Focal length = ����/(1 + ��/��)
Here, WD: Working distance (the distance between lens and object)
W: Width of object
w: Width of sensor (the GO-5000-USB is 12.8 mm)
