Spectral Line Imaging

In this class, we will be concerned with electronic transitions of atoms and ions. They comprise the visible emission from HII regions, planetary nebulae, supernova remnants, and HH objects.

Scanning Electron Microscopy: Principle and Applications in

Scanning electron microscopy (SEM) is an important electron microscopy technique that is capable of achieving a detailed visual image of a particle with high-quality and spatial resolution.

Benchtop Spectrophotometer SpectraVision | Datacolor

Designed for multi-color, textured, small or irregularly-shaped samples, Datacolor SpectraVision combines an advanced hyperspectral spectrophotometer with

How to Do Spectrophotometric Analysis: 13 Steps (with Pictures)

On an analog spectrophotometer, there will be a screen with a needle that moves based on the intensity of light detection. When the blank is in, you should see the needle move to the right.

Design and Optimization of a Linear Wavenumber

We report the design of a high-efficiency spectral-domain spectrometer with cylindrical optics for line scanning optical coherence

Rotational hyperspectral scanner and related image

Recently, a semi-rotational scanning hyperspectral imaging spectrometer was reported27, and its optical disper-sive elements worked in a rotational manner while the camera kept still.

INTRODUCTION Spectroscopy is the study of the interaction between matter and electromagnetic radiation. The types of electromagnetic radiation are often

How Specim line scan hyperspectral cameras work

There are different ways to collect hyperspectral data. Specim products are line-scan hyperspectral cameras. They collect full spectral and spatial information of the target line by line. Sometimes the

How to Use a Spectrometer From Setup to Data Analysis

A spectrometer is a scientific instrument that analyzes light to reveal information about materials. It functions by separating light into its constituent wavelengths, much like a prism splits sunlight into a

Imaging spectrometer

OverviewBackgroundPrincipleApplicationsDisadvantagesSystemsExamplesSee alsoAn imaging spectrometer is an instrument used in hyperspectral imaging and imaging spectroscopy to acquire a spectrally-resolved image of an object or scene, usually to support analysis of the composition the object being imaged. The spectral data produced for a pixel is often referred to as a datacube due to the three-dimensional representation of the data. Two axes of the image correspond to vertical and horizon

Guide to Spectroscopy and Spectral Lines

Editor: Ian Czekala This guide, a continual work in progress like our other guides, aims to provide the context necessary to understand much of the spectral jargon in scientific papers on the arXiv. This
