WARNING

1. 01If the products are unsealed by a private handling & rebuilding,
   you may injure your eyes
2. 02Use extreme caution at all times
   when laser is in use.
3. 03Do not point laser at the eye.
4. 04You should wear proper laser safety
   goggles at all time when the laser is operating

1. 05The infrared laser light may be invisible to the human eye. Therefore, when the power switch is ON, do not watch the laser beam aperture
2. 06Do not place any flammable objects directly in front of the free, non-extended beam.
3. 07Especially with higher power beams

Safety Classification and Measurement methods

As the laser properties, it can concentrate on the unit area. If your eyes are exposed by this high energy, because you may injure your eyes and skin, you have to prevent an accident from taking place by a mark & a label on the product. We define the energy of maximum permissible exposure about eye and skin as MPE, Safety class of Laser Products are classified according to the output power and wavelength of laser beam and measurement distance. We must follow with applicable safety regulations.

Classification

Lanics classify in accordance with the terms of IEC 60825-1(International Electrotechnical commission). Safety class is classified in 1, 1M, 2, 2M, 3R, 3B, 4 classes. Class 1 is lowest class and higher classes are dangerous

Measurement method

After calculating AEL value of class 1 by wavelength, optical power, exposure time of laser system or module, you can compare AEL of class 1 with measured optical power. If the measured optical power is less than AEL of class 1, this laser product is class 1. But if this power is more than AEL of class 1, after calculating again AEL value of class 2, you have to compare with those data. Like this, Safety classes can be classified. Optical power of laser system is measured by below method. Namely, at the measurement distance 100mm, you measure maximum power of aperture 7mm (pupil size)

You must refer the IEC 60825-1 for the exposure time and calculating AEL of each safety class.

Diagram of laser induced damage in biological systems.

대표적으로 2가지의 형태로 손상형태가 발생된다.

1. 01Laser energy is absorbed by the system.
2. 02The absorbed energy produces heat which is conducted to surrounding tissues
3. 03In long-pulse or CW lasers the persistence of thermal front gives rise to a progressively enlarging lesion.
4. 04 In short pulse lasers the high power density gives rise to explosive rupture of cells and damage by physical displacement.

각 등급별 제반사항

Class 1	Considered eye-safe, including while using optical instruments for intrabeam viewing. Normal exposure to this type of beam will not cause permanent damage to the retina (MPE(eye)
Class 1M	Considered eye-safe, Normal exposure to this type of beam will not cause permanent damage to the retina (MPE(eye)). The laser beam should never be intentionally aimed at people.
Class 2	Considered eye-safe about exposure in blinking reflex time(0.25s), including while using optical instruments for intrabeam viewing. The laser beam should never be intentionally aimed at people.
Class 2M	Considered eye-safe about exposure in blinking reflex time(0.25s), The laser beam should never be intentionally aimed at people.
Class 3R	MPE(eye) can be increased to 5 times, including while using optical instruments for intrabeam viewing. Therefore, naturally, the laser beam should never be intentionally aimed at people. And trained person should comply with all of the applicable requirements and precautions.
Class 3B	MPE(eye) can be increased to 5 times, including while using optical instruments for intrabeam viewing. But MPE(skin) can’t be increased to 5 times. And trained person should comply with all of the applicable requirements and precautions.
Class 4	MPE(eye) and MPE(skin) can be exceeded, including while using optical instruments for intrabeam viewing. And specular reflection is dangerous too. In addition precautions of class 3B, you should have protective eyewear and clothing. You must remove all obstacles of inattentive specular reflection beam.
