Optical fibre coupling for opto=electronic component - allows distance between lens and opto=electronic component to be adjusted while maintaining common optical axis

摘要

The optical fibre coupling uses a lens (7, 8) supported by a sleeve (2) between the optical fibre end face and the optoelectric component (9) supported by an adjustment block (13) coupled to the sleeve (2). The coupling between the block (13) and the sleeve (2) allows rotation about the common optical axis to vary the distance between the lens (7, 8) and the optoelectric component (9) while retaining the common optical axis. Pref. the latter adjustment is effected by a setting ring (14). ADVANTAGE - Simple adjustment of coupling.
