Optics is the branch of physics which is concerned with light and it's behavioural pattern and properties. Visit BYJU’S to learn about ray optics, spherical mirrors, optical instruments and more.
The two current facility-class astrophysical missions have focal lengths of 7.5 m (XMM-Newton) and 10.0 m (Chandra). Most X-ray missions use Wolter I type optics (Wolter, 1952) where X-rays are reflected by a paraboloid of revolution to a hyperboloid of revolution and thus to a focus; ...
Two observatory class missions have been operating since 1999 with both imaging capability and high resolution dispersive spectrometers. They are NASA’s Chandra X-ray Observatory, which has an angular resolution of 0.5 arc seconds and an area of 0.1 m2 and ESA’s XMM-Newton which has 3 ...

The "quantum theory of paraxial ray optics according to Dietrich Marcuse" (DM) has no overt relation with the quantum theory of light. Rather, it is a demonstration of a formal similarity between the transition from classical to quantum mechanics of point particles and recovery of wave optics ...

Fortunately, the single-crystal silicon that is a preferred material for use in MEMS12 is also the mainstay of reflective and diffractive X-ray optics for monochromatization, reflection, focusing and dispersion13,14. However, the X-ray applications use silicon single-crystals that are 2–5 ...
1.4.2.1 Geometric optics analysis In this geometric optics analysis, different propagation modes in an optical fiber can be seen as rays traveling at different angles. There are two types of light rays that can propagate along the fiber: skew rays and meridional rays. Fig. 1.4.7A shows an ...
The emitted thermal light cone can be sent to the spectrometer either using reflective optics (Fig. 3(C) and (D)) or optical fibres. A portion of this emission light is then spatially filtered either through slits [66] or pinhole(s) [72] placed at the entrance of the spectrometer. The...
