Annular groove phase mask
This is an Annular Groove Phase Mask (AGPM) which enables high-contrast imaging at very small inner working angles, potentially opening up new possibilities in high-resolution imaging. The part will be installed at the Paranal site onto the near-infrared camera and spectrograph 'CONICA', part of NACO, the VLT’s adaptive optics workhorse instrument.
