MiniScan MS-320X Integration Guide

Calculating The Usable Scan Length Method

Calculate usable scan length as follows (see Figure 2-8 on page 2-11):

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.
