Fixed slit spectroscopy
WebApr 3, 2024 · Direct evidence of time diffraction from the temporal double slit is given by illuminating the sample with a probe pulse (230.2 THz carrier frequency and 1.0 THz bandwidth) of duration 794 fs ... WebNIRSpec's IFU can obtain spatially resolved imaging spectroscopy of a contiguous 3" × 3" area on the sky. To achieve this, the IFU uses specialized optics to reformat the spatial field of view and direct light to the spectrograph optics, which are shared with the multi-object spectroscopy (MOS) and fixed slits (FS) spectroscopy observing modes.

WebThe single object slitless spectroscopy (SOSS) mode of NIRISS uses the GR700XD NIRISS grism to produce 3 orders of cross-dispersed spectra of bright targets in the wavelength range from 0.6–2.8 μm. The grism has a resolving power of R ≈ 700 at 1.25 μm in 1 st order, and at 0.63 μm in 2 nd order. The 3 rd order will generally be too weak ...

WebThe slit and slitless modes have some operational differences. The LRS slit mode is suited to a broad range of spectroscopic observations and therefore supports a wider range of operational choices. The single slit is 4.7" long (3.18 mm; 42.7 pixels) and 0.51" wide (0.33 mm; 4.6 pixels).
WebThe wide field slitless spectroscopy (WFSS) mode of JWST’s Near Infrared Imager and Slitless Spectrograph (NIRISS) enables low-resolution (R ≈ 150) spectroscopy between 0.8–2.2 μm, over the 2.2’ × 2.2’ FOV.
