This technology, based on the Czerny-Turner structure and utilizing the multi-field-of-view theory, can simultaneously detect two different monitoring points. Each point possesses a complete
By utilizing dual channels, this spectrometer enhances detection sensitivity and accuracy, enabling users to identify even the smallest concentrations of elements such as arsenic, mercury,...
Spectrometers are a key device in modern scientific research and industrial applications. To further expand their range of applications, researchers have
An approach that can provide a further decrease of the analysis time, however without compromising neither separation nor peak width, is dual-channel chromatography. In this technique,
It can perform simultaneous analysis of two elements and has a single channel enhancement function, significantly improving testing sensitivity and element detection limit.

The use of a dual-interference channels static Fourier transform imaging spectrometer based on stepped micro-mirror (D-SIFTS) for environmental gas monitoring has the advantages of
The spectrometer is configured with two optical input channels to enable the imaging of two 4-folded spectra on the same focal plane of the BSI-CMOS array detector.
In this study, we design a dual-channel SD-OCT system based on a single spectrometer. Dual-channel spectral data are separated by introducing an optical path offset between two channels
The combination of two spectrometers in dual-laser Raman devices without the need for moving parts represents a significant advancement. This study focuses on design and fabrication of
Sometimes a single channel spectrometer is not enough, for example when you want higher resolution or to do two redundant measurements at the same time. The AvaSpec dual channel spectrometers
To address this challenge, we have developed dual-channel PAM (DC-PAM) that can expand the FOV without compromising the imaging speed, detection sensitivity, or spatial resolution.
Along each path, the light output of the fiber is collimated with a lens into a beam, passes through a cuvette, is refocused with a lens into another fiber, and couples to a grating spectrometer
Figure $11.2.1$ provides a general view of a mass spectrometer in the same way that we first introduced optical instruments in Chapter 7. The ionization of the sample is analagous to the source of photons
Therefore, to satisfy the calibration requirements of a dual-channel portable Raman spectrometer with a wide spectral range, this study designed a calibration method based on an
Dual-channel spectral domain optical coherence tomography (SD-OCT) is one of the effective methods for improving imaging depth and imaging speed. In this paper, we design a dual
Sometimes a single-channel spectrometer is not enough, for example, when you want higher resolution or perform two redundant measurements simultaneously. The AvaSpec dual-channel spectrometers
The mass spectrometer acquisition switches between channels to maximize efficiency. When the data window ends in channel 1, the data window starts in channel 2. Then at the end in channel 2, the
This chapter begins with a discussion of single-channel (scanning-type) spectrometer sources and detectors. It is noted that spectrometer sources are either inherently monochromatic (e.g., tunable
