GLOBAL FOV DIAGRAMS
PRODUCT REFERENCE GUIDE

Example:
The FOV for a Matrix 220 355-0x0 at a reading distance of 200 mm is:
FOV
H
= 2 [(200 mm + 4 mm) * tan (24°/2)] ≅ 87 mm
FOV
V
= 2 [(200 mm + 4 mm) * tan (18°/2)] ≅ 65 mm
GLOBAL FOV DIAGRAMS
NOTE
The following diagrams show the maximum obtainable Field of View for 1D and 2D
codes. Depending on the code resolution, symbology, and number of characters in the
code, the Reading Area can be different from the FOV.
See the
Reading Diagrams, starting on page 112 for specific reading area examples.
The following diagrams are given for typical performance at 25°C using
high quality grade A symbols according to ISO/IEC 15416 (1D code) and
ISO/IEC 15415 (2D code) print quality test specifications. Testing should
be performed with actual application codes in order to maximize the
application performance.
