MICRO SPOT IRRADIATION OPTICS FOR YAG LASER WELDING M-Scope type Y
PRODUCT OVERVIEW
M-Scope type Y is micro spot irradiation optics for YAG laser welding system, best for assembly by micro spot welding of various optical modules, precision component, etc.
As coaxial observation camera and illumination system are equipped, easy and accurate welding process can be realized by observing welding position of precision component directly.
Furthermore, as double beam simultaneous irradiation system is adopted, high accuracy micro welding is realized.
FEATURE
- Easy and accurate welding by direct observation of welding position
- As coaxial observation camera and illumination system are equipped, easy and accurate welding process can be realized by observing welding position of precision component directly. Operator can set the welding position easily, and shot the welding beam accurately.
- Double beam simultaneous irradiation system
- Double beam simultaneous irradiation system, optical beam bifurcation mechanism, is equipped. Through this mechanism, laser beam introduced by single fiber is bifurcated into equally divided double beams in M-Scope type Y. Equally divided double beams are focused on the same plane through the same focusing lens. This system realizes two beam simultaneous and well balanced welding, and contributes to make welding declination minimize and realize high accuracy micro welding.
- Single beam irradiation model is also prepared.
- Prepared two types of irradiation spot magnification
- 1:1 type : irradiate the same spot size of input optical fiber core diameter
- 1:2 type : irradiate half size of input optical fiber core diameter
APPLICATION
- Fixation by YAG welding of various optical modules after optical alignment
- Micro welding of micro spring for HDD unit
- Laser marking
- High accuracy micro welding for general precision components
