Chapter 1 Basic safety instructions
1 BASIC SAFETY INSTRUCTIONS
1.1 Laser safety
The user is responsible for safe operation and for safeguarding the surrounding area against
hazards that can be caused by laser radiation. OEM customers must ensure compliance with
all local and national regulations.
1.2 Laser shutter
The deflection unit is designed to deflect an input laser beam and output it again.
The deflection unit cannot block or weaken the laser beam. To prevent unwanted emission of
the laser beam, above a particular danger class the laser device must be fitted with a shutter
(page 5, Classification of laser devices).
The laser device must be of sufficient quality that the laser beam can only be emitted at the
beam output on the deflection unit.
1.3 Signs
The following signs must be attached to the deflection unit. These signs may not be removed.
Signs that have become illegible must be replaced.
Rating plate
The
rating plate and the identification code printed on it allow
the determination
of the deflection unit type (page 12,
Rating
plate code
). The serial number and the item number are also
used to identify the deflection unit.
The CE symbol confirms the deflection unit's compliance with
European directives. It indicates that the deflection unit is
a
pproved for free trade within the EU.
The seal label warns against unauthorized opening of the
d
eflection unit.
If the seal is broken, all warranty claims against
RAYLASE are void.
At the point where laser radiation is emitted, a laser warning
sign
must be attached. It provides information about the type
of radiation, specific hazards and the degree of protection. The
laser warning sign is attached by the OEM customer in accor
d-
ance
to the laser device's classification (page 5, Classifica-
tion of laser devices
).
The mirrors of the SUPERSCAN II high-speed versions are
made of beryllium. The
rating plate indicates if this applies to
the present deflection unit
(page 13, Detailed Description).
In addition, these
deflection units are provided with the adja-
cent
sign.
Also note
page 7, Special hazards caused by mirrors made
of beryllium
.
4 RAYLASE 2-Axis Deflection Unit SS-II MN065_v1.0.1

Basic safety instructions Chapter 1
Lenses for CO2 laser deflection units with linear translator
modules
are made of zinc selenide. The rating plat
e indicates if
this applies to the present defle
ction unit (page 13, Detailed
Description
). In addition, these deflection units are provided
with
the adjacent sign.
Also note
page 7, Special hazards caused by lenses made
of
zinc selenide.
1.4 Classification of laser devices
The deflection unit can be fitted on various laser devices. Every laser device is assigned to a
particular danger class, which must be specified at the point where laser radiation is emitted,
e.g. using a warning sign. The following classifications are defined in DIN EN 60825-1:
Class
Description
1
The accessible laser radiation is not dangerous under reasonable foreseeable conditions.
1M
The accessible laser radiation is in the wavelength range of 302.5 to 4,000nm. The accessi-
ble laser radiation is not dangerous to the eyes, as long as the cross-section is not reduced
by optical instruments (magnifying glasses, lenses, telescopes).
2
The accessible laser radiation is in the visible spectrum (400 to 700nm). Short-term exposure
(up to 0.25s) is not dangerous to the eyes. Additional radiation components outside the
wavelength range from 400-700 nm meet the requirements for class 1.
2M
The accessible laser radiation is in the visible spectrum from 400 to 700nm. Short-term expo-
sure (up to 0.25s) is not dangerous to the eyes, as long as the cross-section is not reduced
by optical instruments (magnifying glasses, lenses, telescopes). Additional radiation compo-
nents outside the wavelength range from 400-700nm meet the requirements for class 1M.
3R
The accessible laser radiation is in a wavelength range of 302.5 to 10,600nm and is danger-
ous to the eyes. The power or energy is a maximum of five times the limit for permissible
class 2 radiation in the wavelength range from 400 to 700nm.
3B
The accessible laser radiation is dangerous to the eyes and frequently to the skin.
4
The accessible laser radiation is extremely dangerous to the eyes and dangerous to the skin.
Even diffuse scattered radiation can be dangerous. The laser radiation can cause fires or a
risk of explosion.
Note: Bear in mind that the deflection unit changes the position at which the beam is emitted
and the new beam output must be marked with a warning sign showing the appropriate classi-
fication.
Note: The deflection unit can change the classification of the laser device, particularly if it is
fitted with a focusing lens. The laser device may require additional protective equipment as a
result.

Chapter 1 Basic safety instructions
1.5 Laser area
For the purposes of accident prevention, the laser area is defined as the area in which the
maximum permitted radiation value can be exceeded. This is generally applicable for class
3B, 3R and 4 lasers. For class 1 to 2M laser devices, a laser area can be produced by focus-
ing the laser beam.
A sufficient beam intensity produces a laser area that covers the entire radiation angle of the
deflection unit and includes the reflection from all objects that can be exposed to the radiation
as a result. Note that even apparently diffuse surfaces can reflect laser radiation and a laser
beam that has been reflected several times can still be dangerous.
The laser area must be indicated by corresponding warning signs or lamps and protected by
appropriate shading and interlock switches.
No flammable or explosive objects or liquids should be located in the laser area.
This operating manual interprets a selection of accident prevention regulations from the point
of view of using laser deflection units in industrial plants. However, the applicable local and
national standards, rules and regulations are binding.

1.6 Special hazards caused by mirrors made of beryllium
Beryllium mirrors can be destroyed by improper loading. This can lead to a release of berylli-
um dusts. These dusts can cause cancer, are toxic if swallowed and very toxic by inhalation.
Please observe the specified maximum applicable laser power in the data sheet.
Please note also, that soiled mirrors strengthen the absorption of laser power and thereby
increase the risk of destruction of the mirror.
page 21, Special notes for mirrors made of beryllium and lenses made of zinc selenide
1.7 Special hazards caused by lenses made of zinc selenide
Zinc selenide lenses can be destroyed by improper loading. This can lead to a release of be-
ryllium dusts. These dusts can cause cancer, are toxic if swallowed and very toxic by inhala-
tion.
Please observe the specified maximum applicable laser power in the data sheet.
Please note also, that soiled lenses strengthen the absorption of laser power and thereby
increase the risk of destruction of the lens.
Therefore it is essential to ensure suitable suction in the production environment. In addition,
the outer protective glass of the F-Theta lens must be checked for dirt regularly and cleaned if
necessary. For non-removable deposits and after wear, which is caused by frequent cleaning,
the protective glass of the F-theta lens should be replaced.

4 FUNCTIONAL DESCRIPTION
4.1 Laser beam deflection unit
The deflection unit can be used to deflect a laser beam in X and Y directions. This produces
an area within which a laser can be directed at any position. This area is known as the "mark-
ing field" and is shown in Fig. 2. Deflection is performed by two mirrors, each of which is
moved by a galvanometer scanner. The deflection unit has a beam input, into which the laser
beam is fed, and a beam output, through which the laser beam is emitted from the unit after
deflection. Only suitable lasers can be fed into the beam input. Refer to the corresponding
data sheet for details. Depending on the version, the beam output is either open or fitted with
an F-Theta lens or protection glass (page 15, F-Theta lens).

4.2 F-Theta lens
The F-Theta lens is designed especially for use with 2-axis deflection units. It focuses the
laser beam at optimum quality to any position on the marking field. At the same time, it pro-
vides partial optical compensation for the barrel-shaped distortion that is unavoidable when
using a two-axis deflection unit. The remaining distortion (see below) must be compensated
by the deflection unit drive.

Assembly instructions
oBefore installation, check the protection window for dirt, scratches or cracks.
- If the protection window is dirty, it must be cleaned (page 20, Instructions for
cleaning lenses and protective glasses).
- If the protection window is scratched or cracked, it must be replaced.
oBrush the outer thread of the protective glass with a small amount of special grease for
photo-mechanical components. Normal fats are not suitable because they release gases
and thus the optical system can be destroyed.
oScrew the protection window and mount into the beam output of the deflection unit until it is
positioned securely.

Chapter 5 Installation
5 INSTALLATION
Warning:

The laser beam can cause severe injury to the eyes and the skin. Note that
even apparently matt objects can reflect laser beams. All personnel in the
room must wear appropriate laser protection goggles and, if necessary, pro-
tective clothing.

Never look directly in the laser beam, even when wearing protective gog-
gles.

The deflection unit may require the assignment of a different danger class
(page 5, Classification of laser devices) to the laser device.

The laser must be switched off during installation.

We recommend that the laser area is completely protected by an appropri-
ate working chamber. If this is not possible, appropriate protective measures
for the laser class must be implemented.

The mirrors in the deflection unit must move freely after installation of the
deflection unit. No components of the laser device may protrude into the de-
flection unit.

The laser device must be of sufficient quality that the laser beam can only be
emitted at the beam output on the deflection unit.

The "Laser radiation" national accident prevention regulations must be ob-
served.

Connecting cables may not be subjected to mechanical strain.

The deflection unit must be protected against moisture, dust and corrosive
vapors.

The optical components may only be touched when wearing suitable cotton
gloves.

The deflection unit must be protected against static discharge and strong
electromagnetic fields.

The power density of the input laser radiation may not exceed the maximum
permissible power density of the optical components of the deflection unit.

The beam path and the function of the deflection unit must be tested after
installation.
We recommend performing all tests with a danger class 1 or 2 laser to min-
imize the risk of injury. If this is not possible, the laser used must be set to
the lowest possible power. This setting must be secured against accidental
adjustment.
Procedure
oCarefully remove the protective cover over the beam input with a small screwdriver.
oTo install the deflection unit, insert locating pins into the corresponding holes and attach
the deflection unit to the prepared installation surface using screws.
Note: The deflection unit may only be installed using the pins and screws specified by
RAYLASE. Follow the installation drawing supplied.
oFor details about the connection, the deflection unit to a RAYLASE control card, refer to
the corresponding manual.

6 MAINTENANCE AND CLEANING
The subsystem doesn‘t contain any components that require regular maintenance.
Repairs may only be carried out by RAYLASE or RAYLASE certified service centers because
special know-how and comprehensive testing methods are required.
RAYLASE offers worldwide certified service and repair centers.

6.1 Cleaning the housing
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clea
n-
ing, make sure that the laser device is switched off and secured against acc
i-
dentally being swi
tched on.
The deflection unit housing is dust proof. It can be cleaned with a duster. If it is very dirty, the
duster can be moistened with a light and non-aggressive cleaning solution (e.g. soap solu-
tion).
6.2 Cleaning the optical system
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clea
n-
ing, make sure that the laser device is switched off and secured against acc
i-
dentally being switched on.
Dirty optical surfaces result in increased absorption of the laser radiation. This can cause the
dirt to heat up sufficiently, so that it burns into the optical surfaces and damage them perma-
nently.
The following circumstances can cause increased accumulation of dirt:
The ambient atmosphere is contaminated with dirt, grease or other particles.
Vapors and particles are produced while working.
Talking, coughing or sneezing close to optical surfaces.
In general, all contamination of the optical system should be avoided wherever possible.
However, as contamination cannot be avoided completely, the optical system must be
cleaned at appropriate intervals. Regular checking and cleaning of the optical surfaces can
prevent permanent damage.
Note: RAYLASE accepts no liability for damaged optical components!
Note: Damage caused during the laser process, e.g. when processing metals, is irreversible
and cannot be resolved by cleaning.

6.2.1 Instructions for cleaning lenses and protective glasses
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clea
n-
ing, make sure that the laser device is switched off and secured against acc
i-
de
ntally being switched on.
Fingerprints contain aggressive substances that can damage the optical surfaces. Optical
surfaces should therefore only be touched when wearing suitable gloves or with a lens clean-
ing cloth.
oOnly touch the optical elements when wearing suitable cotton gloves and only touch the
edges.
oBlow loose particles from the surface with clean and oil-free compressed air. Note that the
compressed air in workshops can contain oil particles and is therefore unsuitable for clean-
ing the optical system.
oMoisten a suitable lens cleaning cloth with ethanol suitable for cleaning optical compo-
nents.
oPlace one end of the moistened cloth on the optical system and slowly move it over the
optical components. Do not exert any pressure and do not rub the optical components.
oRemove any remaining ethanol residue with a dry optical cloth.
oRepeat the procedure until the surface is completely clean. Use a new cleaning cloth for
each repetition.
6.2.2 Instructions for cleaning mirrors
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clea
n-
ing, make sure that the laser device is switched off and secured against acc
i-
dentally being switched on.
The mirror surfaces are extremely sensitive and may only be cleaned by experienced person-
nel. We strongly recommend sending the deflection unit in to RAYLASE for the mirror clean-
ing, as opening of the deflection unit by unauthorized personnel voids the warranty.
However, if you want to clean the mirrors by yourself, follow the same procedure as for clean-
ing the lens but with even more care (above, Instructions for cleaning lenses and protective
glasses).
