Opto-mechanical device with integrated precision optics and mechanical fine adjustment elements for efficient coupling of a collimated laser beam into either a singlemode fiber with MFD ≥ 2 μm or a multimode fiber.
Performance Features:
Singlemode and multimode laser beam coupler
Inclined or coaxial coupling axis
Integrated tilt and focussing adjustment
A selection of 17 different coupling lenses, partly achromatic or apochromatic
Sensitive alignment of the polarization axes ensured by a circular V-groove with tightly fitting cylinder
Various fiber connector possibilities, for fiber connectors type FC, ST or for extra-terrestrial applications with a DIN-AVIO connector, each with an inclined or coaxial coupling axis. F-SMA type connectors available with 0°-,5°- or 8°-polish e.g. for SMA-905 High Power connectors
Nickel-silver or titanium (amagnetic)
Carbide bearings for the locking screws of the tilt adjustment guarantee a sensitive, repeatable, lateral setting of the focal position
An additional grub screw locks the fiber ferrule, preventing any displacement or rotation
Adapters for various laser types and for many optical bench systems
