From a distance of 10 m, the light spot size can be determined from the angular
extension of the emitted light of typically 0.6 mrad x 2.8 mrad.
°
A = (0.0006 x distance [mm]) +20 mm
Example for 100 m:
A = (0.0006 x 100,000 mm) +20 mm = 80 mm
°
B = (0.0028 x distance [mm]) +10 mm
Example for 100 m:
B = (0.0028 x 100,000 mm) +10 mm = 290 mm

Select and mount the reflector (DL1000 only)
NOTE
You can find suitable reflectors and suitable reflective tape at
.
Reflector tilt
b
To avoid direct surface reflections, mount the reflector with a tilt of approx.
+1° … +3° in one of the 2 axes (horizontal or vertical).
