This article from Wasatch discusses the types of diffraction gratings and how to choose the correct one.
This article from Wasatch explains how OCT angiography works and the applications of it.
Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any collisional event post-ionization, the kinetic energy of the detected electron should be equal to the binding energy of the orbital it was ejected from.

Mass spectrometry is an analytical technique used for chemical identification. By ionizing and fragmenting the sample of interest and measuring the mass-to-charge ratios of the products formed, it is possible to see a ‘chemical fingerprint’ that can help work out a chemical structure. Mass spectrometry can also be used to identify unknown compounds.

This interview describes the High-Performance Polarization Films, their properties, and industrial
applications such as inspection camera and biometrics industries.
Diffuse reflectance spectroscopy is a type of absorption spectroscopy where, rather than measuring the transmitted beam through the sample, the light reflected from the sample is measured instead. It is a common method for measuring opaque samples that absorb too strongly to be measured in transmission.

Bright-field microscopy uses light to produce a dark image against a bright background. Often considered one of the simplest types of microscopy, a bright-field microscope uses an objective, condenser and eyepiece to magnify the image of a sample so the eye can see more minor features.

Phase contrast microscopy manipulates phase shifts in light as it passes through transparent specimens. By converting phase shifts to changes in amplitude (brightness), the method enables scientists to view organic and biological samples with high levels of detail without needing sample preparation, staining, or labeling.

Confocal microscopy is an optical imaging technique that relies on spatial filtering methods to remove contributions to the image from regions of the sample that are not immediately in focus.

Atomic force microscopy (AFM) was first demonstrated in 1985 by Binnig, Quate and Gerber. Since then, the high-resolution non-optical imaging technique has become a powerful tool for surface analysis.
