By Thomas Rasmussen, Ibsen Photonics You are probably reading this guide because you have been tasked to integrate an optical diode-array spectrometer into an analytical instrument.
Here we introduce a new class of spectrometer, which uses the convolution theorem as its unique mathematical foundation.
Computational spectroscopy can act as a bridge between experiments and underlying physical properties, as it provides the theoretical expressions linking observable measurements and
This paper discusses challenges and solutions in spectral convergence, exploring its significance and applications in various scientific and engineering domains.
In this presentation, we demonstrate how we utilize the convergence science and technology to overcome the limit of diffractive optics, making the size and cost of spectrometer, compact and
Spectrometer An XPS spectrometer A spectrometer (/ spɛkˈtrɒmɪtər /) is a scientific instrument used to separate and measure spectral components of a physical
Introduction Time-of-flight mass spectrometry (TOF-MS) is widely employed for mass analysis of various ion species as it enables us to measure their mass spectra in a wide mass range instantaneously.
The rapid advent of machine learning (ML) and artificial intelligence (AI) has catalyzed major transformations in chemistry, yet the application of these methods to spectroscopic and
In this paper, we want to explore the effect of varying probe convergence and spectrometer collection semi-angles on the on-axis vibrational energy-loss spectrum from a crystalline h-BN
Reflectron time-of-flight mass spectrometer (RTOF-MS) is a powerful tool to achieve high resolution in mass analysis of various ions. As it is often s

In high school chemistry, students are taught that the convergence limit in the emission spectrum of an element can be used to determine the first ionization energy.
The grating facilitates primary spectral dispersion, whereas the metasurface enables off-axis convergence at different wavelengths. Grating–metasurface coupling effectively enhances the
We report the design of a high-efficiency spectrometer for high-resolution spectral-domain optical coherence tomography (SD-OCT). The advantages of the proposed spectrometer are
Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material
We have developed a compact, asymmetric three-channel echelle spectrometer with remarkable high-spectral resolution capabilities. In order to
There is a notion of convergence for spectral sequences, and by carefully choosing how we construct one, we can ensure our spectral sequence converges to something useful.
This study aims to develop an intelligent adjusting system based on global optimization algorithm for high energy resolution X-ray spectroscopy beamline commissioning.
