The effective aperture angle for the SLG 422/ 425I-P is +/- 4,0° (when L > 3,0 m) as provided by the IEC 61496-2.
Install the SLG 422/ 425I-P away from reflective surfaces at an effective aperture angle of +/- 5,0° to take misalignment
during installation into account. See following table:

Formula:
a = tan 2,5° x L [mm]
a = Minimum distance to reflective surfaces
L = distance between SLG 422/ 425I-P and mirror ULS
