Walden All-Sky Imager
The small, all-sky fisheye spectral imager, is a compact instrument capable of imaging an entire 180° field of view, simultaneously.
Optically, the all-sky field of view is imaged onto a 1392 x 1040 pixel Sony CCD at F/0.95.
A telecentric design ensures that all the chief rays are at normal incidence at the image plane, allowing the use of narrow bandpass interference filters (<2nm) in the five-position filter wheel.
