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 - consisting of a linear translator module and a deflection unit - 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 7, 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.

Chapter 1 Basic safety instructions
6 RAYLASE 3-Axis Subsystems for Laser Beam Deflection MN025 / v2.1.0
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 linear translator mod-
ule and the deflection unit (page 15, 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 7,
Classification of laser devices).
In the high-speed versions of the subsystem the mirrors are
made from beryllium.
To indicate this, these subsystems are labeled with the adja-
cent sign.
Also note page 9, Special hazards caused by mirrors made
of beryllium.
Lenses for CO2 laser deflection units with linear translator
modules are made of zinc selenide.
To indicate this, these subsystems are labeled with the adja-
cent sign.
Also note page 9, Special hazards caused by lenses made
of zinc selenide.

Basic safety instructions Chapter 1
MN025 / v2.1.0 3-Axis Subsystems for Laser Beam Deflection 7
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.

Chapter 1 Basic safety instructions
8 RAYLASE 3-Axis Subsystems for Laser Beam Deflection MN025 / v2.1.0
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.

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 50, 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 release of dust
with hydrogen selenide and selenium dioxide. 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 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.

MN025 / v2.1.0 3-Axis Subsystems for Laser Beam Deflection 19
4 FUNCTIONAL DESCRIPTION
4.1 Laser beam subsystem
The laser beam subsystem consists of the deflection unit and the linear translator module.
The deflection unit 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 and Fig. 4. Deflection is performed by
two mirrors, each of which is moved by a galvanometer scanner. RAYLASE provides the ap-
propriate deflection unit for the deflection properties required. The laser beam subsystem can
therefore be fitted with different deflection units. Refer to the rating plate to identify the deflec-
tion unit used (page 15, Rating plate code).
The focusing properties of the laser beam subsystem are determined by the linear translator
module and, on some versions, also by an F-Theta lens on the deflection unit. The linear
translator module is fitted with one or two focusing lenses. An additional lens with linear
movement allows the focusing length to be adjusted.
Because of their different focusing properties, the subsystems are divided into four groups:
AXIALSCAN (standard)
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 44, Manually
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 26, Protection window).
AXIALSCAN (water cooled)
Like the standard AXIALSCAN, the water cooled version is also fitted with a motorized adjust-
able lens. Unlike the standard version, the lens is moved using two galvanometer units to
increase the speed.
As well as this version designed for high speed, a version designed for a high laser power is
available.
AXIALSCAN (motorized)
On this version of the AXIALSCAN, the entire linear translator can be moved by a motor. This
enables motorized adjustment of the size of the operating field (page 5, Motorized field size
adjustment).
FOCUSSHIFTER (standard)
On the FOCUSSHIFTER, an F-Theta lens on the deflection unit is used for focusing and to
set the size of the operating field. With this configuration, the linear translator module can be
used to change the focusing plane. This allows almost three-dimensional operations to be
performed. For example, this is useful when creating a 3D image in a glass block or for deep
processing of materials.
Subsystems are available as analog or digital versions. Refer to the following functional prin-
ciples.
