3. Instrument Overview Leverages Adaptive Secondary for Sensitive, High Contrast Imaging Short Wavelength Channel (SWC): 3-5 microns, 4 HAWAII-2RG at 10 mas /pixel Long Wavelength Channel (LWC): 8-25 microns Single MegaMIR detector at 30 mas /pixel

4. Operational Modes

5. High Contrast Performance Achieved via Phase Apodization Coronagraphy (Codona) and Nulling depending on application.
