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 subsystem is designed to focus and deflect an input laser beam and output it again.
The subsystem 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 subsystem.
1.3 Signs
The following signs must be attached to the subsystem. These signs may not be removed.
Signs that have become illegible must be replaced.
The rating plates and the identification codes printed on them
can be used to determine the type of the subsystem
(page 11, Rating plate code). The serial number and the
item number are also used to identify the subsystem.
The ground symbol identifies the ground connection on the
subsystem. This connection can be connected to the laser
housing via a plug connection to increase the interference re-
sistance.
The CE symbol confirms the subsystem's compliance with
European directives. It indicates that the subsystem is ap-
proved for free trade within the EU.
The seal labels warn against unauthorized opening of the
subsystem. If a seal is broken, all warranty claims against
RAYLASE are void.
A laser warning sign must be attached at the point where
laser radiation is emitted. This 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
accordance with the laser device's classification (page 5,
Classification of laser devices).

Basic safety instructions Chapter 1
MN049 / v1.0.0 3-Axis Subsystem AS-50 for Laser Beam Deflection 5
1.4 Classification of laser devices
The subsystem 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 302.5nm to 4,000nm. The ac-
cessible laser radiation is not dangerous to the eyes, as long as the cross-section is not re-
duced by optical instruments (magnifying glasses, lenses, telescopes).
2
The accessible laser radiation is in the visible spectrum (400nm to 700nm). Short-term expo-
sure (up to 0.25s) is not dangerous to the eyes. Additional radiation components outside the
wavelength range from 400nm-700nm meet the requirements for class 1.
2M
The accessible laser radiation is in the visible spectrum from 400nm to 700nm. Short-term
exposure (up to 0.25s) is not dangerous to the eyes, as long as the cross-section is not re-
duced by optical instruments (magnifying glasses, lenses, telescopes). Additional radiation
components outside the wavelength range from 400nm-700nm meet the requirements for
class 1M.
3R
The accessible laser radiation is in a wavelength range of 302.5nm to 10,600nm and is dan-
gerous 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 400nm 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 subsystem changes the position at which the beam is emitted and
the new beam output must be marked with a warning sign showing the appropriate classifica-
tion.
Note: The subsystem 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.

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
subsystem 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 subsystems in industrial plants. However, the applicable local and na-
tional standards, rules and regulations are binding.

4 FUNCTIONAL DESCRIPTION
4.1 Subsystem
The subsystem can be used to deflect a laser beam in X and Y directions. This results in a
two-dimensional plane, within which a laser can be directed at any position. This area is
known as the "operating field" and is shown in fig. 3. Deflection is performed by two mirrors,
each of which is moved by a galvanometer scanner.
The focusing properties of the laser beam subsystem are determined by the linear translator.
The linear translator is fitted with one or two focusing lenses. An additional lens with linear
movement allows the focusing length to be adjusted.
In these systems, the lens with linear movement is moved within a small range by a galva-
nometer unit. This so-called linear translator allows the focusing length to be adjusted to the
relevant deflection angle of the deflection unit. Compared to an F-Theta lens, this provides a
relatively large operating field, in which the laser beam can be optimally focused at every
point. The size of the operating field is set manually during installation (page 21, Adjusting
the field size). The optical system and the electronic components of the deflection unit can be
protected against contamination by installing a protection window over the beam output
(page 14, Protection window).

5 INSTALLATION
The following sections describe installation of the subsystem in a laser device. When doing
this, it is essential to check that the laser beam is input into the subsystem and output from
the subsystem centrally. Otherwise, misalignment of the laser beam will occur each time the
focus is changed. The subsystem is adjusted prior to delivery and do not need to be adjusted
in the field.
Warning:
The laser beam can cause severe injury to the eyes and the skin. Note that
even apparently matt objects can reflect the wavelength of laser beams. All
personnel in the room must wear appropriate laser protection goggles and, if
necessary, protective clothing.
Never look directly at the laser beam, even when wearing protective
goggles.
The subsystem may require the laser device to be assigned to a different
danger class (page 5, Classification of laser devices).
The laser must be switched off during installation.
We recommend that the laser area is completely protected by an
appropriate 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
deflection 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" accident prevention regulations (BGV B2) must be
observed.
Connecting cables may not be subjected to mechanical strain.
The subsystem must be protected against moisture, dust and corrosive
vapors.
The optical components may only be touched when wearing unpowdered
latex gloves.
The subsystem 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 in the subsystem.
The beam path and the function of the subsystem must be tested after
installation.
We recommend performing all tests with a danger class 1 or 2 laser to
minimize 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.

Installation Chapter 5
MN049 / v1.0.0 3-Axis Subsystem AS-50 for Laser Beam Deflection 17
5.1 Mount subsystem
oCarefully remove the protective cover over the beam input with a small screwdriver.
oTo install the subsystem, insert locating pins into the corresponding holes and attach the
subsystem to the prepared installation surface using screws.
Note: The subsystem may only be installed using the pins and screws specified by
RAYLASE. Follow the installation drawing supplied.
5.2 Checking the beam coupling
5.2.1 Preparation
In order to be able to check the beam coupling, all components located in the beam path must
be removed. Take note of the following steps:
oRemove the Focusing lens (1)
oOpen the cover (2)
oMark the position of linear translator (3)
oRemove linear translator (3)
oProtect the focusing lens and linear translator against dust.

5.2.2 Checking procedure
The following steps are used to check that the laser beam is coaxial to the linear translator. If
this is not the case, the input point and, if necessary, the input angle of the laser beam must
be adjusted as described below.
Warning:
The laser beam can cause severe injury to the eyes and the skin. Make sure
that all personnel in the laser area are wearing appropriate protective goggles
and, if necessary, protective clothing.
Fig. 6
Checking the
beam coupling

Installation Chapter 5
MN049 / v1.0.0 3-Axis Subsystem AS-50 for Laser Beam Deflection 19
Checking the input point
oPlace a piece of thermo transfer paper behind the cross hair device (A).
oInsert the cross hair device at position (A).
oTurn on the laser at low power for just long enough for a clearly visible effect to appear on
the thermo transfer paper (C).
oCheck the beam diameter. It must be smaller than the input aperture specified in the data
sheet.
oCheck that the laser beam appears in the center of the cross hairs. If not, the input point of
the laser beam needs to be adjusted.
Checking the input angle
oPlace a piece of thermo transfer paper behind the cross hair device (B).
oInsert the cross hair device in the lens holder.
oInsert the lens holder in its slot.
oTurn on the laser at low power for just long enough for a clearly visible effect to appear on
the thermo transfer paper.
oCheck the beam diameter. It must be smaller than the input aperture specified in the data
sheet. If the beam diameter at the beam output is greater than that measured at the beam
input, this indicates excessive divergence of the laser beam. In this case, reduce the beam
diameter, e. g. by using beam expander with lower amplification.
oCheck that the laser beam appears in the center of the cross hairs. If not, the input angle of
the laser beam needs to be adjusted.
Optimizing settings
oRepeat the entire adjustment process until optimum laser beam input point and input angle
settings are achieved.
5.2.3 Assembly
oAssemble the linear translator and the focusing lens in vice versa order as described in the
disassembly (page 17).
oYou must now set the field size (page 21, Adjusting the field size).
