MAINTENANCE 

Maintenance may only be carried out by trained personnel. These trained personnel must be familiar 

with the general safety rules for electrical engineering, optics, mechanics and laser technology. 

  

6.1

 

Cleaning 

 WARNING 

Risk of injury due to incorrect cleaning 

Incorrect cleaning can cause damage to optical elements (e.g. due to scratching). Damaged optics 
can then be destroyed during operation, deflecting the laser beam onto the protective housing. This 

can result in a risk of burns or uncontrolled escape of laser radiation from the destroyed protective 
housing. 

 

Only clean optical components if you have sufficient knowledge and experience of handling 
optics for laser components and laser systems.

G2 -01 0.1

 

 

Precisely follow the instructions for cleaning the optics set out in this chapter.

G2-01 0.2

 

  

6.1.1

 

Cleaning the housing 

1.

 

When cleaning the housing, do not touch the optical surfaces. Cleaning these is a separate task. 

2.

 

Before cleaning, ensure that the laser system is switched off and secured against being 
accidentally switched on again. 

3.

 

Clean the deflection unit housing with a soft lint-free duster. 

4.

 

If there is more severe dirt, moisten the cloth with a non-aggressive cleaning solution (e.g. soap 
solution). 

  

6.1.2

 

Cleaning the lens 

The lens is very sensitive and may only be cleaned by experienced professionals. 

  

1.

 

Before cleaning, ensure that the laser system is switched off and secured against being 
accidentally switched on again. 

2.

 

Only hold the optical assembly with powder-free latex gloves and only by the edge, as fingerprints 
contain aggressive substances that can damage the optical surfaces. 

3.

 

Carefully remove the lens and place it in a safe location protected from dust. 

4.

 

Blow off any loose particles from the surface with clean and oil-free compressed air. Note that the 
compressed air in workshops may contain oil particles and in this case is unsuitable for cleaning 

optics. 

5.

 

Moisten a suitable lens cleaning cloth with high-purity isopropanol or acetone. 

6.

 

Place one end of the moistened cloth on the optics and pull it slowly across the optics. Do not 
exert any pressure and do not rub it over the optics. 

7.

 

Remove any remaining solvent residue with a dry lens cleaning cloth. 

8.

 

Repeat this procedure until the surface is completely clean. Use a new lens cleaning cloth each 

time.
