Coronagraphs
List of Available Coronagraphs
The SCExAO instrument is equipped with several coronagraphs, which operate across the near-IR (y-K bands) :- The Phase induced amplitude apodization complex mask coronagraph (PIAACMC) provides small IWA and high throuput in H band
- The Vortex coronagraph provides small IWA and high throuput in H band
- The Lyot coronagraphs provide high throughput, robust performance across the near-IR (y-K bands)
- The Shaped Pupil coronagraph provides robust performance across the near-IR (y-K bands)
For a detailed evaluation of SCExAO coronagraphs available to users, see this report
