HEXAFLEX: Fiber spectrograph

First light: 1 May 1989.

Designed and built by: IAC

Description:

HEXAFLEX is an upgrade of FLEX. It consists of two fiber bundles mounted simultaneously on the spectrograph, which allow one to change the spatial and spectral resolution without any modification in the spectrograph´s configuration. At the focal plane, the 61 fibers of each bundle are arranged in a hexagonal lattice, which permits regular and symmetrical mapping.
