Connecting the Lens 

The camera supports lenses with C-Mount or CS-Mount connectors.  

Refer to section 2.4 for instructions on connecting the lens. 
 
Hints for Selecting the Lens 

In order to take full advantage of the quality and the features of the 
camera, it is important that you select a lens that is optimized to your 
application. In the following section we have provided some helpful 
hints on how to proceed in the selection of a suitable lens. 
 

 

Focal Length 

With the focal length you determine the visible screen window, or 
image portion captured by the camera. 
The focal length depends on the size of the CCD chip, the distance 
from the object and the focal length of the lens being used. 
The screen window should be optimized so that the object being 
captured is always fully visible on the screen, and also so that the 
amount of unused screen space surrounding the object is 
minimized. Otherwise the object would be displayed unnecessarily 
small and the camera’s resolution would not be fully utilized. 
 
The FireWire-CAM-011H / -012H / 111H and 112H are both 
equipped with a 

“ – CCD-sensor. 

The following formula can be used to calculate the required focal 
length f from the desired frame width B and the distance between 
the object and the lens (L) (all values in millimeters): 
 

L

B

mm

f

=

8

,

4

 

 
Round the resulting value up to the next available focal distance. 
This will give you a slightly bigger screen window than necessary 
but it ensures that the entire object will be captured on the screen.
