MOCRO SPOT IRRADIATION OPTICS FOR YAG LASER WELDING

Realize high accuracy YAG laser welding of precision parts such as various optical modules, harddisk drive, etc..

M-Scope type Y is the micro spot irradiation optcis for YAG laser welding system,
best for assembly by micro spot welding for various optical modules, precisioncomponent, etc. As coaxial observation camera and illumination are equipped, easyand 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 TV camera and illumination are equipped, easy andaccurate welding process can be realized by observing welding position ofprecision component directly.
○Double beam simultaneous irradiation system●Double beam simultaneous irradiation system by beam bifurcation is equipped.
laser beam introduced by single ﬁber is bifurcated into equally divided double
beams through optics. 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.

Among electronic components, optical components such as optical modules are composed of many optical components such as LDs, lenses andoptical ﬁbers. In this assembly, it is necessary to adjust the position of each part by using actual light and ﬁx it by YAG welding so that theoptimum optical coupling state is achieved. For this reason, YAG welding ﬁxation with high accuracy is required. M-Scope type Y is designed forhigh precision YAG welding and ﬁxing of such precision parts.
