A 128 fiber Slit-Plate assembly, Kinematic mount

This assembly includes 128 fiber slit plates, kinematic mount, cable clamps, lenslet arrays, and pigtail fibers. Each array has 32 fibers glued and bonded in place for secure fit. The base plate integrates into the carrier assembly for spectrograph fit-up. By Robin Lafever, SSL/LBL.
