6.1.3 Avoiding total reflection – oscillating-mirror scanner
For the device with oscillating mirror, the laser beam exits at an angle of 90° to vertical.
In addition, the swivel range of ±20° is to be taken into account.
This means that in order to be on the safe side and to avoid total reflection, the device with oscillating mirror
must be inclined upward or downward 20° … 30°!
