4-General Safety Instructions

1、Specular Reflection

There are often numerous secondary laser beams produced at various angles in the output port of the laser. These divergent beams are produced when the

primary beam of laser reflects off a smooth surface, and they are called specular reflections. Although these secondary beams may be less powerful than the

total power emitted from the primary beam, the intensity may be great enough to cause damage to the eyes and skin as well as surface of materials.

WARNING:

◎ You must exercise caution to avoid/minimize specular reflections as these laser radiations are invisible!

2、Safety Instructions of Accessories

The photosensitive elements integrated in laser-related optical accessories may be damaged by laser exposure, such as video cameras, photomultiplier tubes,

and photodiodes. Attention should be paid to related device protection.

WARNING:

◎ The Maxphotonics MFSC laser light is strong enough to cut or weld metal, burn skin, clothing and paint. In addition, this light can ignite volatile substances

such as alcohol, gasoline, ether and other solvents. During the operating process, the flammable materials around the laser must be isolated.

CAUTION:

◎ The output of the laser is delivered through a lens with an anti-reflection coating. If the backward-stage light path of your laser has the optical lens, please 

strictly inspect the lens of the output head and the backward-stage lens of the laser, and ensure that there is no dust and any other impurity on the lens.

Please note that any macroscopic attachment may cause extreme damage to lens or burn the laser or any backward-stage light path equipment.

◎ For cleaning instructions of the lens, please refer to the “Optical Fiber Connector Inspection and Cleaning Guide”.

◎ Hot or molten pieces of metal may be produced when the laser is under operation. Exercise caution if debris is produced in operation.

◎ When you carry out commissioning and calibration of the laser output, you must set the laser output at low power level and then gradually increase the

output power during checking the quality of the light spot emitted from the laser via an infrared viewer.

WARNING:

◎ Make sure that the individual protective equipment meets the output power and wavelength range of the laser.

◎ Never look directly into the optical fiber or the collimator, and make sure you wear the safety protective glasses in each operation.
