2GENERAL SAFETY INFORMATION
2.1 Designated use
The deflection unit is intended to deflect laser radiation within an appropriate operating range for the
purposes of material processing.
The deflection unit is designed as a sub-assembly for laser systems and is classed as an incomplete
machine as defined in the Machine Directive. Each product version may only be operated with the
wavelength specified in the type code (see page 19, Signage) and with the specified beam diameter
(see page 21, Technical data).
Depending on the version, the SUPERSCAN IV is designed for lasers with wavelengths of 355 nm to
11,000 nm and an input aperture of 10, 15, 20 or 30 mm.
2.2 Classification of laser systems
The deflection unit can be installed on a range of different laser systems. Every laser system is assigned
to a laser class, which must be specified at the output location of the laser radiation (e.g. using a laser
warning sign).
The following laser classes are defined in DIN EN 60825-1 and described in DGUV Regulation 11:
Class Description
1 The accessible laser radiation is not dangerous under reasonably foreseeable conditions.
1M The accessible laser radiation is in the wavelength range 302.5 nm to 4,000 nm. The accessible laser
radiation is not dangerous to the eyes, provided the beam cross-section is not reduced by optical
instruments (e.g. magnifiers, lenses, telescopes).
2 The accessible laser radiation is in the visible spectral range (400 nm to 700 nm). Short exposure times
(up to 0.25 s) are not dangerous to the eyes. Additional beam components outside the wavelength
range 400 nm to 700 nm meet the conditions for Class 1.
2M The accessible laser radiation is in the visible spectral range 400 nm to 700 nm. Short exposure times
(up to 0.25 s) are not dangerous to the eyes, provided the beam cross-
section is not reduced by optical
instruments (e.g. magnifiers, lenses, telescopes). Additional beam components outside the wavelength
range 400 nm to 700 nm meet the conditions for Class 1M.
3R The accessible laser radiation is in the wavelength range 302.5 nm to 106nm and is dangerous to the
eyes. The power or energy is a maximum of five times the permitted Class 2 radiation limit in the
wavelength range 400 nm to 700 nm and five times the Class 1 limit for other wavelengths.
3B The accessible laser radiation is dangerous to the eyes and frequently also to the skin.
4 The accessible laser radiation is very dangerous to the eyes and dangerous to the skin. Diffusely
scattered radiation can also be dangerous. The laser radiation can cause a risk of fire and explosion.
Note that the deflection unit changes the beam output location of the laser system. The new beam
output must be indicated by a laser warning sign on the deflection unit, stating the corresponding
classification.
The use of a deflection unit can change the laser system’s laser class. This can necessitate additional
protective measures.

2.3 Laser area
For the purposes of accident prevention, the laser area refers to the area in which the maximum
permitted radiation value can be exceeded. Laser systems must be assigned and marked according to
their laser class and use.X2-010.1
With a corresponding beam intensity, the laser area is defined by the total radiation angle of the
deflection unit and by the reflection of all objects that can be irradiated by it. It is important to note
that, in addition to reflective surfaces, matt and dark surfaces can also reflect laser radiation and that a
laser beam reflected several times can still be dangerous. In addition, the deflection unit can be
destroyed by back reflection.X2-010. 2
The laser area must have permanently and legibly attached markings in accordance with
DIN EN 60825-1. Laser systems must be fitted with the protective mechanisms required for safe
operation according to their class and use.X2 -010 .3
No combustible or explosive objects and liquids may be located in the laser area, as the energy of the
laser beam can ignite them.X2-010.4

2.4 Hazards due to laser radiation
WARNING
This chapter describes hazards that can result due to interaction with the higher-level laser system.
The operator of the higher-level laser system is responsible for safe operation and for securing the
surrounding area to prevent hazards that can be caused by laser radiation. They must ensure
compliance with all applicable conditions, regulations, laws, standards and directives.X2-020
2.4.1 General safety measures
The following general safety measures are to be observed:
To ensure that the laser beam is immediately switched off in the event of a fault, the laser process
must always be monitored. Alternatively, the entire beam path can be in a radiation-proof housing.X2-030 .1
The laser system must be designed in such a way that the laser beam can only be emitted at the
beam output on the deflection unit.X2-030.2
Appropriate protection mechanisms must be in place to prevent unauthorised activation or use of
the laser system.X2-030.3
The maximum permitted input beam diameter may not be exceeded.X2-03 0.4
If the materials to be processed can result in toxic vapours, safe extraction of these must be
ensured. Oxidising material processing and processing with material removal that is precipitated
onto the optics must be handled properly.X2-030.5
2.4.2 Measures to prevent uncontrolled escape of laser radiation.
If the mirrors in the deflection unit are destroyed, the laser beam no longer exits the deflection unit at
the intended beam output but remains inside the deflection unit. This leads to heating and, in some
cases, destruction of the housing and can lead to uncontrolled escape of the laser beam.X2-040
To prevent destruction of the mirrors, the following points must be observed:
At the laser beam input, it is essential that the laser beam strikes the centre of the mirrors. If the
laser beam strikes a mirror towards the edge, the mirror can be overheated and destroyed.X2-04 0.1
To prevent a loss of control, the plug connections to the deflection unit may only be disconnected
when the laser system and the power supply are switched off.X2 -04 0.2
The deflection unit should always be operated with a lens or protective window.X2-040. 3
The maximum permitted laser power may not be exceeded.X2 -040.4
The deflection unit must be installed in such a way that the mirrors cannot come into contact with
liquids. Liquids change the reflective properties of the mirrors, which can lead to them being
destroyed by the laser beam.X2-040. 5
Before processing highly reflective materials, RAYLASE must be contacted as reflections can lead to
the destruction of the deflection unit.X2-040 .6
In general, correct and careful handling of the optical components must be ensured, particularly
during maintenance and cleaning work. Contaminated or scratched optics can absorb
unacceptable amounts of laser power and thus be destroyed.X2-040.7

2.5 Required training and instruction of operating personnel
The deflection unit is designed exclusively for use in an industrial environment.X2-050. 1
Start-up, operation, installation, maintenance and repairs may only be carried out by trained personnel
who have been instructed by the laser protection officer and are sufficiently qualified to perform the
relevant work.X2-050.2
2.6 Required protection measures
If present in the laser area, protective equipment such as laser protection goggles or special protective
clothing is required. The required protective equipment is stipulated by the laser protection officer
based on the individual hazards caused by the laser equipment. The laser area must be marked so that
the required protective equipment is clearly indicated to all personnel who intend to enter the laser
area.
2.7 Behaviour in case of destroyed zinc selenide (ZnSe) lenses
WARNING
Zinc selenide properties hazardous to health
Destruction of zinc selenide lenses can result in dust containing hydrogen selenide and selenium
dioxide. This dust can be carcinogenic and is very toxic when inhaled.02-010
To improve the optical properties of the material, zinc selenide is frequently given an anti-reflective
coating that may contain thorium fluoride. Thorium is a radioactive element. The quantity of thorium
contained in the coating and the relative size of the decomposed area of the lens surface mean that,
even in the worst cases, the resulting radioactive exposure levels are normally well below the limits set
out in the Radiological Protection Ordinance.
If lenses are damaged:
1. Switch off the laser system immediately.
2. Leave the room for at least 30 minutes.
3. Never remove the lens or the protective window from the deflection unit. Toxic dust or fragments
may have been produced in the deflection unit.
4. If the deflection unit should be opened and fragments fall out, the fragments must only be
collected up using appropriate protective clothing and breathing apparatus and disposed of as
hazardous material in line with the applicable conditions, regulations and legislation.
5. Label the defective deflection unit with a clear warning notice and send the deflection unit to
RAYLASE in air-tight protective packaging.
6. The personnel charged with uninstalling the deflection unit must wear appropriate protective
clothing and breathing apparatus.
7. The room in which the zinc selenide lens was destroyed must be adequately cleaned,
decontaminated and ventilated.
8. Wear gloves and mouth protection when carrying out the subsequent tasks.
9. Carefully collect all fragments and pack them in an air-tight sealable container.
10. Clean all contaminated system components and surfaces with a damp cloth and pack the cleaning
cloths in an air-tight sealable container.
11. Send the containers to the supplier of the optics. They are responsible for proper disposal of the
material.

3.2.2 F-Theta lens
The optional F-Theta lens is specially designed for use with 2-axis deflection units. It focuses the laser
beam at maximum quality on any position in the processing area. At the same time, it partially optically
compensates for the barrel-shaped distortion that is unavoidably produced by 2-axis deflection units.
The remaining distortion (see figure) must be compensated by the deflection unit.

3.2.3 Protective window
For operation of the deflection unit without F-Theta lens it is strongly recommended to use a
protective window for safety reasons and in order to protect the mirrors from contamination. If the
protective window itself becomes contaminated, it must be cleaned (see page 39, Cleaning the
protective window).

RAYLASE is continuously working on optimizing the manufacturing
process for our products in order to save energy and CO2. Among
other things, we do not use surface finishing processes of a
cosmetic nature. This can lead to optical deviations in the surfaces,
which, however, have no influence on the function of the product.
