1. Total reflection mirror(quartz): generally used on the optical path of marking machine, welding machine and cutting machine, forming a resonant cavity with the half mirror to generate laser light. K9 total reflection lens is generally used in marking machines, usually single-sided coating. However, if the power of the marking machine is relatively high, it is 75 watts or 100 watts. The full-reflection mirror with single-sided coating may burn out the red light indicator. In this case, it is recommended that customers use the double-reflection total reflection. mirror. In addition, some customers require a red light indicator with a high light transmittance. It is recommended to use a blue-coated total reflection mirror. Because of its high power and high energy, the high-power cutting machine is easy to damage because it is not resistant to high temperatures. Quartz's total reflection mirror has a high damage threshold and can withstand high-power laser energy, so it is an ideal total reflection lens.

2. Half reflection mirror (quartz): generally used in a marking machine, a cutting machine and a welding machine to form a resonant cavity with the total reflection mirror to generate a laser.
K9 reflection mirror is commonly used in marking machines and typically use an output rate of 15%. But there are also 10% and 20% output rates. With 15% output rate, the laser output power is relatively stable and relatively strong, and the loss to the module is relatively small, so the module uses a longer life. With 10% output rate, the output power is very stable, and the loss to the module is also the smallest, but the output power is not high, which is suitable for the occasion of marking with low power. With 20% output rate, the output power is very strong, suitable for the marking of metal depth, but the lens with this output rate has the largest loss to the module, affecting the service life of the module, and the stability of the light output is also closed. To a certain impact. In the factory report of the module's production company, they generally use this output rate lens for testing, in order to display the test report very beautiful. In short, choose half-mirrors with different output rates, each has advantages, customers please choose according to their own needs. Because of its high power and high energy, the high-power cutting machine is easy to damage because it is not resistant to high temperatures. Quartz's half mirror has a high damage threshold and can withstand high power laser energy, so it is an ideal semi-reflective lens. Generally, a 50% output rate is sufficient for cutting a thin plate, but if you want to cut a thicker plate, it is recommended to use 70%. Of course, with a lens with a higher output rate, the loss of the laser bar will be correspondingly larger, and the attenuation of the laser bar will be faster.
