X-RAY MICROSCOPE - A LITERATURE REVIEW

Abstract

X-ray microscopes produce enlarged images of small objects.This microscope makes use of the emission of X-ray from a point source to cast an enlarged image on a phosphor screen. Microscope is an instrument that produces magnified images of small objects, permitting the observer an extremely close view of small structures at a scale suitable for examination and analysis .Recently, most of the soft X-ray microscopes use a synchrotron radiation source to provide the X-ray. X-rays penetrate objects far easier compared to visible light.Thus X-ray microscopes can image the interior of samples which seems opaque for visible light. X-ray microscopes have excellent powers of penetration due to radio waves that can pass easily through most matter, excluding good conductors such as metals.They allow us to study the bulk regions of thick samples in their natural environment. A major disadvantage of x-ray microscopy compared to electron microscopy is its inability to produce real-space images of the objects that are being focused ,there are no appropriate lenses available. The aim of this review article is to analyse the applications of X-ray microscopes in various fields.
