Engineering Key Points (I)
Infrared Instrument
• Cryogenics using a large cryostat (> 1 cubic meter)
• Complex optical system
• Diffraction limited (high Strehl values requested @ imaging and spectroscopy modes)
• Relatively large FOV in imaging mode (up to 41x41 arcsec)
• High throughput requested
• Integral Field Spectrograph
• An Integral Field Unit is needed (very complex all-reflective optical system @ 77K, field slicer, diffraction limited)
• Complex mechanical system
• Very high stability and repeatability of the final image on the detector is requested
FRIDA Engineering StatusFRIDA Engineering Status 121217/05/0717/05/07
Engineering Key Points (II)
• Imaging and Integral Field Spectroscopy Simultaneous Modes
• A large number of cold subsystems inside the cryostat
• Three imaging scales
• Large number of lenses and a cold mechanism to change camera barrels
• Low, medium and high spectral resolutions
• Cold grating carrousel mounting an imaging mirror and 7 gratings (~100x45 mm)
• 2 dof needed to tilt the high resolution gratings

Integral Field Unit (IFU) Concept
FRIDA Engineering StatusFRIDA Engineering Status 161617/05/0717/05/07
FRIDA IFU Layout
• FOV between 0.66x0.60 arcsec and 2.64x2.40 arcsec
• 30 slice mirrors (cylindrical). 66 pixels/slice
• 30 pupil mirrors (off-axis spheres), round aperture
• 30 field mirrors (spherical), rectangular aperture
• Relay optics adapts the input scale to the slices size (~350 m)
• Total IFU amplification is x1
• IFU is nearly telecentric (pupil plane on the grating surface for all cameras)
• Design similar to FISICA (UF)
