Astrophotonic Spectrographs [PDF]
Astrophotonics is the application of photonic technologies to channel, manipulate, and disperse light from one or more telescopes to achieve scientific objectives in astronomy in an efficient and cost-effective way.

The Magellan Echellette (MagE) spectrograph is a single-object optical echellette spectrograph for the Magellan Clay telescope. MagE has been designed to have high throughput in the blue; the peak throughput is 22% at 5600 A including the telescope. The wavelength coverage includes the entire optical window (3100 A - 1 micron).

Compact Spatial Heterodyne Spectrographs for Future Space-Based Observations: Instrument Modeling and Applications [PDF]
High-resolution spectroscopy employing spatial heterodyne spectrographs (SHS) holds significant promise for forthcoming space missions, building upon its established track record in science applications.

Characteristics of the Belgrade Astronomical Observatory's stellar spectrograph [PDF]
In this paper the main features of the new SpectraPro-750 spectrograph of Belgrade Astronomical Observatory are described. The instrumental profile of the spectrograph for the 1200 l/mm grating is determined using a fiber optic bundle with fibers ...

Doppler cross-correlation spectroscopy as a path to the detection of Earth-like planets
In the middle of the 20th century, a paradigm shift appeared concerning the expected frequency of planetary systems in the galaxy ...a shift induced by the observation of the rotational velocities of low main sequence stars (Struve 1952)!At the same time,

Mobile and high-spectral-resolution Fabry–Pérot interferometer spectrographs for atmospheric remote sensing [PDF]
Grating spectrographs (GS) are presently widely in use for atmospheric trace gas remote sensing in the ultraviolet (UV) and visible spectral range (e.g. differential optical absorption spectroscopy, DOAS).

Optical schemes of spectrographs with a diffractive optical element in a converging beam [PDF]
Optical schemes of spectrographs based on transmission concave holographic gratings working in converging beams are considered. General description of the design techniques are provided. Each of them is supported by a certain example with calculation and

The optical designs of two new types of mass spectrographs were studied. The first is a system that possesses a specially shaped magnet output boundary to satisfy the double-focusing condition for a wide mass range. The focal plane is usually curved.
