2021年6月19日 · Abstract: in this post we describe the application of the Thunder Optics SMA Spectrometer and the Spectragryph software in transmittance measurements. We will apply the technique of transmission spectroscopy to the study of some optical filters.

Ultraviolet Visible Near-Infra red (UV-Vis-NIR) spectroscopy is useful to characterize the absorption, transmission, and reflectivity of a variety of technologically important materials, such as pigments, coatings, windows, and filters.

In this white paper I will present two alternative compact spectrometer designs based on transmission gratings rather than reflective gratings and explain the distinct benefits of the transmission grating based geometries:

View PDF Abstract: Spectral analysis is one of the most powerful tools for studying and understanding matter. Traditional mode-locked optical frequency combs, which feature broad spectra and low repetition rates, have ...

2017年1月20日 · This article outlines how the Rhea spectrometer series can be used in many different ways to make transmission measurements of translucent materials and how it can be customized to take the best measurements possible.

To get absolute calibrated spectra the results should be corrected for: - If working with a gas discharge source: gas absorption (ie Xe); - Air absorption of residual gas in the chamber; - CCD sensitivity; - filter transmission of used filters; - grating efficiency;

2024年11月11日 · Why do transmission grating based spectrometers provide unique solutions? Explore our white paper, “Transmission grating based spectrometers“, where we present two compact spectrometer designs based on this exceptional grating and describe the distinct benefits that such spectrometers offer over traditional reflective grating-based spectrometers.

Thorlabs' HG10 Holographic Grating Spectrometer is a fiber-based, high-speed spectrometer that provides sub-nanometer resolution in the optical range of 810 to 965 nm. Its acquisition speed of up to 130 kHz, external synchronization options via a TTL trigger input, and rigid design make it …

We offer market-leading spectrometers like the Shamrock Series, a Czerny-Turner spectrometer for Raman spectroscopy, the Kymera Series, a Transmission Optical spectrometer for versatile imaging and the Mechelle Series, a Echelle spectrometer for high-res detection.

4 天之前 · Transmission spectroscopy, which does not require any additional accessories, is most frequently used to obtain IR spectra of NPs. Figure 1 depicts the schematic representation of FTIR techniques employed for the analysis of nanoparticles, namely, transmission spectroscopy (TS), attenuated total reflection (ATR) and photoacoustic spectroscopy ...
