The angle of entry is set within a range of 5°≤ β ≤ 85°.
At β > 30°, the direction of entry is calculated as being perpendicular.
At β < 30°, the direction of entry is calculated as being horizontal.
The minimum distance is the distance to the farthest optical axis, and the height of the optical
axis is calculated using ≤ 1000 (mm)
The height of the lowest optical axis is calculated using H ≥ 15 ( d – 50 ) (mm) .
