Paper Abstract
Lessons learnt during the design, integration and commissioning of the Southern African Large Telescope’s Fiber
Instrument Feed and its guidance probe are presented along with initial on-sky performance results.
Advances over the original design include enhanced target acquisition efficiency by including an imaging camera
directly on the fiber-positioning stage, use of linear optical encoders on all motion stages, thermally compensated
designs, a guidance probe optical design with much improved throughput as well as a new non-contact metrology
process to accurately model the guider.
The system has since been successfully used in commissioning the SALT High-Resolution Spectrograph.
