Focusing lens is widely used in machinery and equipment using carbon dioxide laser. Its main function is to focus the carbon dioxide laser into a point, gather the energy of the carbon dioxide laser, make it play a great role and complete the laser processing technology. Focus lenses commonly used in light guide arm, laser cutting machine, laser punching machine and laser engraving machine are divided into pvd zinc selenide focus lens and cvd zinc selenide focus lens. No matter which focus lens needs coating, coating on focus lens is very important, which directly determines the quality of focus lens. There are many kinds of materials for coating focusing lenses, which can be divided into many kinds of coating films according to different materials. Jinghang Laser is familiar with many kinds of coating films, which are used in the production of laser tubes, laser lenses, silicon reflective lenses and light guide arms. The laser transmittance of coated focusing lens is as high as 98%, while that of uncoated focusing lens is less than 80%, which shows the importance of coating focusing lens.
