Product description
The formation of droplets of heavy contamination can be detrimental to the reflection
behaviour. Take the necessary organisational measures to avoid the formation of drop-
lets on the deflector mirrors. The deflector mirrors are available as accessories (see
page 128f.).
Deflector mirrors reduce the effective scanning range. The effective scanning range
depends on the number of deflector mirrors in the light path (see chapter 5.4 “Scanning
range” on page 42ff).
You can extend the M4000 Advanced A/P multiple light beam safety device with a maxi-
mum of one deflector mirror.
