The viewing angle has a tolerance of
±
1° depending on the reading distance.
FOVx = 2 [ (d + d0) * tan (ax/2) ]
where:
FOV
x
= horizontal, vertical or diagonal FOV
α
x
= horizontal, vertical or diagonal viewing angles.
d
= reading distance (in mm) from window surface to code surface
d
0
= offset (in mm) from center of lens to external window surface
