Optical element module, and apparatus and method for fixing optical element |
摘要 |
A semiconductor laser ( 41 ) is fixed onto a base part ( 22 ) with a submount ( 32 ) and a reference optical axis ( 5 ) is determined by the semiconductor laser ( 41 ). A groove ( 222 ) having a U-shaped section is formed on a bonding part ( 221 ), and solder ( 31 ) is applied in the groove ( 222 ) and melted and a collimator lens ( 42 ) supported by a supporting arm ( 61 ) is moved to the groove ( 222 ). A light beam emitted from the semiconductor laser ( 41 ) is guided through the collimator lens ( 42 ) to an image pickup part ( 7 ), where an image representing the state of the light beam is acquired. The collimator lens ( 42 ) is positioned with respect to the reference optical axis ( 5 ) on the basis of the image and fixed onto the base part ( 22 ) out of contact therewith, with the solder interposed therebetween. This simplifies a structure of an optical element module ( 11 ) in which the collimator lens ( 42 ) is positioned with respect to the reference optical axis ( 5 ) with high accuracy.
