Focusing head．Optical Fiber
▶ Focusing head
The focus head assembly efficiently collects laser beam coming from the optical fiber. There are various types available, differing by the work distance and the focal distance involved. There is a standard type, and there is also a CCD camera version that allows checks of the work point with a CCD camera during welding operations.
▶ CCD camera loaded unit
There are three types of illumination method. The one that best suits the application can be selected. Also, the most appropriate lens diameter and protective glass shape for each can be selected. Furthermore, a large color monitor has been made standard to improve the ease of viewing.
Standard model : Epi-illumination type
- Input and output lens diameter: Φ30mm, Φ40mm, Φ50mm
- Protective glass shape: square, round
For work with curved surfaces : For work with curved surfaces
- Input and output lens diameter: Φ30mm, Φ40mm
- Protective glass shape: round
- Ring illumination shape: Φ75mm
- Note: For some models, certain ring illumination sizes do not allow certain lens diameters.
For work with high reflection ratios : Side illumination type
- Input and output lens diameter: Φ30mm, Φ40mm
- Protective glass shape: square, round
▶ Optical fiber
For most applications we recommend the SI (Step Index) Optical Fiber. Bending the optic fiber less than the permitted bend radius could cause a breakage. Please use it at a larger radius.
