FRIDA is a diffraction-limited imager and integral-field spectrograph for the adaptive-optics focus of the Gran Telescopio Canarias. In imaging mode FRIDA provides scales of 10, 20 and 40 mas/pixel and in IFS mode spectral resolutions of about 1200, 4000 and 30,000. Coronographic masks are available in both modes for highcontrast images. FRIDA is undergoing systems integration and is scheduled to complete system testing at the laboratory in December 2024 and to be delivered to the telescope shortly thereafter. In this contribution we present a summary of its design, fabrication, current status and potential scientific applications.
FRIDA is an infrared (0.9 microns- 2.5 microns ) imager and integral field spectrograph that will work in concert with the Gran Telescopio Canarias Adaptive Optics system (GTCAO). We describe the assembly, integration and validation of the FRIDA optics: the manufacture of the optical components at our UNAM workshops; the opto-mechanical assembly including the alignment and interferometric validation tests; the assembly and testing of all of the optics and mechanisms on a the cold bench at room temperature. Finally, the cryogenic subsystems validation, prior to the final assembly and integration of the instrument inside the FRIDA cryostat.
