X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
An X-ray microscopy image of a living 10-days-old canola plant [1]. An X-ray microscope uses electromagnetic radiation in the X-ray band to produce magnified images of objects. . Since X-rays penetrate most objects, there is no need to specially prepare them for X-ray microscopy observatio

The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
The three main technologies employed for long-range shooting—the bolt-action rifle, telescopic rifle scope and machined cartridge ammunition—were developed in the nineteenth century. The first bolt-action rifle was produced in 1824 by the German firearms inventor Johann Nicolaus von Dreyse. The first documented telescopic rifle sight was ...
"The commanding officer of USS John S. McCain was relieved Aug. 30 due to a loss of confidence in his ability to command the guided-missile destroyer," the Navy said in a statement on the same day.
A combination of an exceptionally dry period - downtown Los Angeles has only received 0.16 inches (0.4cm) of rain since October - and powerful offshore gusts known as the Santa Ana winds have ...
A thermographic weapon sight, thermal imagery scope or thermal weapon sight is a sighting device combining a compact thermographic camera and an aiming reticle. [1] They can be mounted on a variety of small arms as well as some heavier weapons. [2] As with regular ultraviolet sensors, thermal weapon sights can operate in total darkness.
