Notes:
1. Contrast measured as Mean Reflective Difference (MRD) at 650 nm.
2. Near ranges on lower densities largely depend on the width of the bar code and the scan
angle.
3. Working range specifications: Photographic quality symbols, pitch = 10°, skew = 0°,
roll = 0°, ambient light < 150 ft. candles, and temperature = 23 °C.
NOTE Not optimized for omnidirectional mode.

Usable Scan Length

The decode zone is a function of various symbol characteristics including density, print contrast, wide-to-narrow
ratio, and edge acuity. Consider width of decode zone at any given distance when designing a system.
