laser damage to the eyes and skin Human skin and eyes exposed to the laser can be harmed. In general, human eyes are more fragile than skin. Even with scattered laser light, long-term damage to the human eye cannot be underestimated. If there is a metallic substance in the processed material, more attention should be paid to the metal reflection. In the far ultraviolet and far infrared bands of the spectrum, the lens is susceptible to damage. However, the most important concern is the region of the retinal spectral damage, from about 400 nm (violet light) to 1400 nm (near infrared), and includes the entire visible region of the spectrum.
The necessary protective measures are what the operator should consider. The easiest way is to order laser safety glasses. For lasers in the high power or visible range, a protective window is essential.
According to the CDRH standard, for a fiber-optic communication system using a 1550 nm laser and a single-mode fiber, the output power of the first-stage product should be below 8.5 mW, and the fourth-order is greater than 500 mW. According to the IEC standard, for a fiber-optic communication system using a 1550 nm laser and a single-mode fiber, the output power of the first-stage product should be 10 mW or less, and the level of less than 50 mW is 3, and the second-order is greater than 500 mW.
The laser marking machine is a high-tech product. It is the most advanced laser marking equipment. After investigation by researchers, the laser marking machine generally does not harm the body, but it does not mean that there is no point. Hazard, it is possible to do any work, but for the application of laser marking machine, as long as the operation is right, buy a good quality product, you can use it with confidence.
