“…We would also like to note -while the design in the paper was focused on Raman spectroscopy using a 785nm excitation source, the design process can easily be generalised to any application that benefits from or traditional use an MM fibre input. Other similar uses we are exploring include a small testbed spectrograph aboard the i-INSPIRE 2 satellite in low Earth orbit [15] and the development of stable radial velocity spectrographs [16].…”

We report on the development of a compact (volume ≈ 100 cm 3 ), multimode diffraction-limited Raman spectrograph and probe designed to be compact as possible. The spectrograph uses 'off the shelf' optics, a custom 3D-printed twopart housing and harnesses a multi-core fibre (MCF) photonic lantern (multimode to few-mode converter), which slices a large 40 µm multimode input into a near-diffraction-limited 6 µm aperture. Our unique design utilises the hexagonal geometry of our MCF, permitting high multimode collection efficiency with near-diffraction-limited performance in a compact design. Our approach does not require a complex reformatter or mask and thus preserves spectral information and throughput when forming the entrance slit of the spectrograph. We demonstrate the technology over the interval 800 nm to 940 nm (200 cm −1 to 2000 cm −1 ) with a resolution of 0.3 nm (4 cm −1 ), but other spectral regions and resolutions from the UV to the near infrared are also possible. We demonstrate the performance of our system by recording the Raman spectra of several compounds, including the pharmaceuticals paracetamol and ibuprofen.

Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution

et al. 2021

View full text Add to dashboard Cite

We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most fundamental epochs of cosmic evolution: the formation of the first galaxies (at z 6; comsmic dawn), and at the peak of galaxy formation activity (at redshift z∼1-3; cosmic noon). By way of NIR observations (λ=0.8-2μm), it is possible to study the UV Lyman-α region in the former, and the optical rest-frame in the latter, allowing us to extract fundamental observables such as gas and stellar kinematics, chemical abundances, and ages, providing a unique legacy database covering these two crucial stages of cosmic evolution. The need to work in the NIR at extremely low flux levels makes a ground-based approach unfeasible due to atmospheric emission and absorption. Only with the largest facilities of the future (e.g. ELT) will be possible to observe a reduced set of targets, comprising at most of order thousands of galaxies. Likewise, from space, the small field of view of JWST and its use as a general purpose facility will yield a rather small set of high quality NIR spectra of distant galaxies (in the thousands, at best). Our project (codename Chronos) aims to produce ∼1 million high quality spectra, with a high S/N in the continuum, where information about the underlying stellar populations is encoded.
