The LBTEK reflective fiber collimator can operate in the 250 nm-450 nm wavelength range, with optional output spot sizes available. It is compatible with fibers featuring FC/PC, FC/APC, or SMA connectors. As shown in the assembly diagram, the LBTEK reflective collimator can be paired with various mirror mounts to enable three-axis angular adjustment of the output spatial beam.
- Working wavelength 250 nm-450 nm
- Multiple output spot options available
- Fiber connector: FC/PC, FC/APC, SMA optional
