6.2.7 Distance between BCL and Bar Code

Principle Orientation of the Scan Line to the Bar Code

Depending on application, either the line scanner or line scanner with oscillating mirror version of the
BCL is used. Figure 6.4 represents the principle orientation of the BCL based on the two scanning
processes to the bar code on the object.

Figure 6.4: Orientation of the BCL based on the two scanning processes to bar code and direction of
transport

Read distance to the bar code and opening angle

a

The distance between the reading window of the BCL and the bar code may not exceed the technical
limits specified for the device. Section Figure 4.3:, on page 34 and Section 4.3.4, on page 40 represent
the variation of reading field height with read distance at various resolutions (module widths).
Figure 6.5 defines the read distance a from the reading window and the opening angle

a

for both scan-

ning processes.

Figure 6.5: Definitions of read distance a and opening angle

a

The line scanner’s useful opening angle

a

is max. 56° and that of the line scanner with oscillating mir-

ror is max. 50°. The reading field height (scan line length) depends on the read distance due to the V
principle of beam deflection.
