Researchers have developed calibration equations that let a simple ATR-FTIR spectrometer quantify strontianite and witherite ...

At f/8, every lens produces an identical 10.7-micron diffraction blur on your sensor regardless of focal length or aperture ...

The "Secrets Series" on image-based visual inspection. This time, we cover lenses and depth of field.IntroductionWhether rule ...

Abstract: Diffraction imaging provides a direct means of detecting local heterogeneities such as faults, fracture zones, and erosional surfaces, which are critical for seismic interpretation and ...

ResoFox is a Python-based graphical tool designed for theoretical analysis of neutron powder diffractometers. It focuses on evaluating the influence of optical components—namely collimators and ...

Neutron diffraction is a vital technique for studying crystal structures and magnetism. Resolution and flux are two critical parameters in the design of neutron diffractometers. While Monte Carlo ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Materials are made of tiny crystallites and non-crystallites; the former gives distinct patterns on interaction with X-rays, as the X-ray wavelength is identical to the inter-atomic spacing in ...

The transmission of viral diseases is highly unstable and highly contagious. As the carrier of virus transmission, cell is an important factor to explore the mechanism of virus transmission and ...
