Aperture Window
To clean the aperture output window use a soft cloth
and medical grade isopropyl alcohol. If necessary, you
can remove the aperture output window by loosing the
4 socket bolts and clean the inside of the window as well.
Cooling Fans
Use compressed air for cleaning the bottom part of the
laser system. There are cooling fans located at the bottom
of the heat sink and they are vital for correct operation
of the laser system. Please always ensure that they are
spinning freely.
You should perform this service every 2 months if the laser
is used regularly or even more often if it is used in dusty
conditions.
Internal Optics
The cleaning of the internal optical components should
be performed by an authorised technician only. Incorrect
techniques or wrong choice of chemicals used for cleaning
could cause serious damage to the laser system. Due
to the fact that the optical compartment is split and sealed
from the rest of the laser system it shouldn’t be necessary
to perform this procedure more often than once a year.
Drying agent cartridge
Drying agent cartridge (silica gel desiccant) helps to prevent
water condensation inside the optical compartment of the
laser system, which is much needed in high temperatures
and high humidity environments. The desiccant cartridge
is installed on the inside of the optical compartment cover.

It is essential to regularly inspect the
condition of the silica gel granules
inside the cartridges. That can be done
through the opening in the middle of the
cartridge. If the colour of the granules
inside the cartridge is green, instead
of brown (brown is when they are dry),
it means they are soaked, and they must
be dried out. Inspect the cartridge every
time you open the optical compartment,
or at least once a month.
The drying out process is pretty simple:
1. Detach the cartridge from the cover and place it into
the conventional oven - do not use microwave!!!
2. Heat the oven to 120ºC (250ºF) and leave the cartridge
inside for about 2-3 hours, until all the moisture
is released.
3. Insert the cartridge back into its place and close the
optical compartment cover as soon as the cartridge
cools down. That way, it will absorb the maximum
amount of moisture from the inside of the optical
section.
!
If the granules don’t turn brown during
this process, they must be replaced with
new ones.
Maintenance: no user serviceable parts inside.
