ZnSe Laser Focus Lens

Product Introduction:

Laser lens is widely applied in laser processing, like cutting, drilling, welding, sculpture, etc. Two series of flat-convex and crescent-shaped lens have been developed to satisfy the market needs. The laser lens can withstand high density and is hard to fall off. To provide better service, the company has improved the design of laser lens from two sides – diffraction and aberration and has developed a series of products with the minimum actual focal spot diameter.
Note: custom-made laser lens is also available.


Laser lens is widely used in laser CO2 laser processing industry, including laser cutting machine, engraving, marking, drilling and other laser machine.
