The fiber couplers allow a direct diode fiber coupling of single emitters with only one lens element. The couplers consist of a monolithic glass block with two opposite crossed cylindrical surfaces and passive alignment edges. The light of the fast and slow axes is collimated by one cylindrical lens to produce a symmetrical focus.

Coupling the light of multiple emitters, bars or mini-bars into an optical fibre generally requires complex optical systems with a variety of components. LIMO has developed a unique cost-effective optical solution for mini-bars which consists of one single component only.
