3-Axis Subsystem AS-50 for Laser Beam Deflection 

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 

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). 

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.  

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.
