Design of the Scanner Opening 

Second, the scanner must be positioned so that the scan volume and illumination light 
will cover the entire bar code.  The scan volume is shown in 

tion of the Scan Volume and the illumination light is called the Field of View. Design­
ing around the scanner Field of View is explained more in the following section, 

. 

A typical system uses the scanner mounted inside a host enclosure with an opening for 
the scanner Field of View to exit the scanner window and read bar codes. If the scanner 
is flush against the opening, it should be the size of the scanner window at a minimum, 
but only exposing as much of the front surface of the scanner as necessary. Additional 
clearance in the opening can also be considered for the speaker opening.  

The design and placement of the scanner opening within a host enclosure is critical for 
optimum system performance. Use the detailed dimensions shown in 

, to design the host enclosure and scanner opening along 

with the following guidelines. 

•  The opening must not block any of the outgoing illumination light, described by 

dimensions of the scanner Field of View. 

•  Ensure that there are no reflective surfaces around the area of the scanner opening. 

•  The minimum opening size must increase as the distance between the scanner and 

the window increases. This is necessary to accommodate the width and height of 
the scan volume. 

•  The opening or other parts of the host enclosure must not enter the Field of View 

in order to allow the bar code image to be captured by the scanner.
