How to identify the type of laser pointer?
The "Product Safety Law" stipulates that Laser pointer must be classified correctly. The standard DIN 60825-1 is decisive here. Therefore, as a user, you can see which laser category the device belongs to in the operating instructions and the markings on the laser pointer. If there are no operating instructions in the local language or the laser device does not have a label, the pointer should not be used. By the way: Marks with Roman numerals (such as I or II) do not comply with the law. This type of label indicates that the laser device is not classified according to the standards applicable in Europe.

1、Class 1 laser output: <25 microwatts, wavelength: 400-1400nM **, eye safety under reasonably foreseeable conditions.
2、Level 2 laser power: maximum 1 mW*, wavelength: 400-700nM **, classification: low performance. Because of the blink reflex under reasonably foreseeable conditions, the eyes are safe.
3、2M power laser: maximum 1 mW*, wavelength: 400-700nM **, classification: low performance. Due to the blink reflex, the eyes are safe. The use of optical auxiliary equipment such as a magnifying glass or binoculars may be dangerous.
4、3R laser power: 1-5 mW *, wavelength: 302nM **-10 microns, classification: due to blinking reflection, it is not safe for the eyes. Looking directly at the beam can be dangerous.
5、Class 3B laser power: 5-500mW *, wavelength: 302nm **-10 microns, classification: looking directly at the beam is dangerous. It may be harmful to the skin.
6、Level 4 laser power:> 500mW *, wavelength: 302nm **-10 microns, classification: high performance. Very dangerous to eyes and skin. Risk of fire.
