Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Mass Analyzers: Common Types

671
The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Overview of Microscopy Techniques

10.6K
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Summary

Low energy bremsstrahlung emission

Area of Science:

  • Atomic and Molecular Physics
  • Quantum Optics
  • Spectroscopy

Background:

  • Bremsstrahlung emission can impact electron spectrometer and monochromator performance.
  • Classical theory may not fully account for all relevant emission modes.

Purpose of the Study:

  • Investigate the influence of low energy bremsstrahlung emission on electron spectrometers and monochromators.
  • Explore novel radial modes in quantum mechanics not covered by classical theory.

Main Methods:

  • Analysis of multi-photon events.
  • Quantum mechanical modeling of wave packet propagation.
  • Description of wave packet shielding via extended half-life.

Main Results:

  • The main azimuthal (organ pipe) mode's effect is likely negligible.

  • A new radial mode, revealed by quantum mechanics, poses a potential concern.
  • Wave packet shielding enhances stability.

    • Conclusions:

    • Bremsstrahlung emission, particularly a novel radial mode, can affect electron spectroscopy performance.
    • Quantum mechanics provides a more complete picture of these phenomena.
    • Cavity effects may offer further suppression of unwanted emission.
