This is a the root page for all DKIST facility instruments.

Visible Broadband Imager (VBI)

The Visible Broadband imager is an imaging filtergraph that is operated between 393.4 nm and 656.3. It is located in the Coudé lab.

The VBI is separated into two distinct components (blue and red) because each has its own optical bench and each picks off its share of the beam at different locations along the science beam.

VBI Blue Channel

The blue channel operates between 393.4 nm and 486.1 nm.

VBI Red Channel

The red channel operates from 600 to 860 nm and is optimized for 656.3 nm.

Visible Spectropolarimeter (ViSP)

The ViSP is a grating-based slit spectrograph that provides polarimetric data in all four Stokes vectors, I, Q, U, and V. By scanning the sun’s image perpendicular to the slit orientation it can produce IQUV images. It is located in the Coudé lab.

Near Infrared Spectro-Polarimeter (NIRSP)

Similar to the ViSP, Near-IR Spectro-polarimetry is accomplished using two distinct instrument packages, both located in the Coudé lab.

Diffraction Limited Near-IR Spectropolarimeter (DL-NIRSP)

The DL-NIRSP is operated and room temperature and uses the deformable mirror and Coudé bench light distribution following the DM. The wavelength range is 900nm to 2300nm.

Cryogenic Near-IR Spectropolarimeter (Cryo-NIRSP)

The Cryo-NIRSP is cryogenically cooled. This is the primary coronal instrument, capable of high signal-to noise coronal spectro-polarimetry.

Visible Tunable Filter (VTF)

The Visible Tunable Filter is a narrow-band filtergraph that operates between 500 and 900 nm. It provides diffraction-limited images as narrow as 3 pm and can perform full Stokes vector polarimetry. It is located in the coudé lab.
