5.1 Lens Angle
The lens angle is the recording angle of
the camera lens in vertical direction.
To select the right lens for the camera
the lens angle is most important. A
zoom lens has a variable lens angle, a
fix lens has not.
From the horizontal distance of the camera to the finish line (L1), the width of the finish and
the camera height the camera angle can be calculated.
Our most commonly used C-Mount zoom lens Z75 has an adjustable camera angle from 7°
(75 mm) to 31° (12.5 mm).
Camera angles for C-Mount Lenses:
•
8.5 mm 1360 pixel resolution about 58°
•
12.5 mm 1360 pixel resolution about 31°
•
16 mm 1360 pixel resolution about 28°
•
75 mm 1360 pixel resolution about 7°
•
160 mm 1360 pixel resolution about 3°
To adjust the camera it is very important that the camera is horizontally leveled. To guaran-
tee this, the camera is equipped with a spirit level on its back.
