YAG Laser Welder
Focus head, Optic fiberThe focus head assembly efficiently collects laser beam coming from the optic 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.
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:Ø30mm, Ø40mm, Ø50mm
Protective glass shape: square, round
For work with curved surfaces : For work with curved surfaces
Input and output lens diameter:Ø30mm, Ø40mm
Protective glass shape:round
Ring illumination shape:Ø75mm
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:Ø30mm, Ø40mm
Protective glass shape:square, round

Optic fiberFor most applications we recommend the SI (Step Index) Optic Fiber. Bending the optic fiber less than the permitted bend radius could cause a breakage. Please use it at a larger radius.
| Optic fiber model | SIH-02CA | SIH-03CA | SIH-04CA | SIH-06CA | SIH-08CA |
| Core diameter | Ø0.2mm | Ø0.3mm | Ø0.4mm | Ø0.6mm | Ø0.8mm |
| Permitted bend radius | 100mm | 150mm | 200mm | ||
| External diameter | Ø8mm | ||||
A feature that detects breaks in the optic fiber and an optic fiber device diagnostic feature (optional) immediately report problems or abnormalities with an optic fiber.
