The laser die cutting machine is guided and reflected by the optical path and is focused on the processed object by the focusing lens group for the laser die cutting machine.The laser must be cut by the high power density energy generated by the laser focusing for the laser die cutting machine, so the focusing lens on the laser head has a cutting effect for the laser die cutting machine.

What is the material of the focusing lens for the laser die cutting machcine?

The focus mirror provided by the laser is mainly made of glass, quartz, gallium arsenide and zinc selenide for the laser die cutting machine.

Glass and quartz materials are mainly used for YAG lasers with a wavelength of 1.06μm. The price of glass lenses is relatively lowfor the laser die cutting machine. but the power consumption is also low; the price of quartz lenses is higher and the power is higher for the laser die cutting machine.

Gallium arsenide and zinc selenide are mainly used for carbon dioxide laser with a wavelength of 10.6μm for the laser die cutting machine. It is generally believed that the use of these two materials is equivalent for the laser die cutting machine.except that gallium arsenide is not transparent to red light, and zinc selenide can transmit red light for the laser die cutting machine.
