MS-120X and MS-220X Integration Guide
Calculating The Usable Scan Length Method
Calculate usable scan length as follows (see
L = 2 x (D+d+B) x Tan (A/2)
where:
D = Distance (in inches) from the front edge of the host housing to the bar
code.
d = The host housing’s internal optical path from the edge of the housing to the
front of the MiniScan scanner.
B = Internal optical path from the scan mirror to the front edge of the MiniScan
scanner.
A = Scan angle in degrees.
Note:
Usable scan length determined by this formula, or 90% of scan line
at any working distance. This formula is based on good quality
symbols in the center of the working range and length of bar code.
