Abstract

The Arizona Lenslet for Exoplanet Spectroscopy (ALES) has been conceived of as an integral field spectrograph (IFS) that can be integrated with the existing 1-5 micron imaging camera LBTI/LMIRcam. Retrofitting an IFS to an existing camera poses interesting optical design issues. We have developed four reflective magnifier designs to create the proper scale for each spaxel of the IFS across the operational wavelengths of ALES. The lenslet design utilizes the flexible nature of silicon etching to provide aberration correction of images across the field of view that are introduced by inserting these magnifiers into the existing LMIRcam optical system. Finally, direct vision prism designs have been developed to provide suitable dispersion modes for the reference science cases of ALES.
