摘要：

Spectrographs are integral in panoramic surveys. An optimized spectrograph design can facilitate the observation of faint objects. One such optimization lies in its bundle of optical fibers and their numerical apertures (NA). Low NA fibers are less commonly used and studied, but can be advantageous in terms of cost and precision. Here, we describe the properties of 0.12 NA and 0.22 NA fibers with different input beam f-ratio, quantities of wraps, and bend radii.
