Introducing the acronym or Characteristic of the Co2 laser lens that many people may not recognize. It is important to know the following.

FL = focal length

MD = mounting distance

Dia. = Diameter

CT = Center thickness

ET = Edge thickness

Laser cutting The focal length used is important for laser cutting. Therefore, we should have the understanding to choose.

If you choose not to work, it will affect the work. Frequent focus in the market is usually to use focal lengths of 5 "7.5" and 10 ",

so we should choose the correct thickness of the material. The thicker the work,

we should use a longer focus, such as cutting steel thickness of not more than 6 mm.

Should use FL 5 "or cut steel thickness 16 mm should use FL 10" to achieve.

Example

7.5" Focal Length (inch)

5.0" Focal Length (inch)
