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
.

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.
