Heat exchanger fans.
If the LiDAR is in a dusty environment, it may be necessary to blow the dust from around the heat exchanger fans with
an air duster. The fans should also be checked routinely to make sure that they are both spinning without obstruction.
Wiping brush.
The wiping brush can be removed if it is full of dust, or badly deformed. There are 2 small grub screws that hold in
place. The brush can be cleaned in water, and then set straight whilst wet and then dried. It should then maintain the
shape. A replacement brush is available if it is damaged.
Vinyl tape.
The vinyl tape around the bottom of the white enclosure is not a seal – it is there just to prevent a build up of dust from
becoming trapped between the enclosure to base plate junction. Replacement vinyl tape can be used to replace it if it
becomes damaged. Regular tape as used for car striping is recommended 1” wide.
Optical output window.
The optical performance will not be affected too badly from beaded standing water on the output window as illustrated
below provided the fractional coverage of the clear aperture is not too high.
The output window has a hard anti-reflection coating on the outer surface. The coating is reasonably robust but should
it be deemed necessary to clean it, the procedure below should be adopted:
The surface of the window should be flooded with IPA or an equivalent optical cleaning solution and left to soak for a
short period of time to loosen any debris which might have adhered to the surface. Wiping of the window should be
done with a soft lens tissue. This cycle should be repeated until a satisfactory result is achieved.
LiDAR enclosure.
If the LiDAR’s enclosure becomes excessively dirty, then it can be washed down with a sponge and water. Detergents
used for washing dishes for example, should be fine to use. Scouring pads or abrasive cleaning products should not
be used.
Purging.
If the internal humidity of the system becomes high, then it may be necessary to purge the system with dry air. An air
inlet on the
, and one of the enclosure screws will be removed during the purge.
A suitable connector for use with the purge inlet will have been supplied with the system. If it can’t be found, this is the
part that is needed:
