An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the irradiance of the light but could also, for instance, be the polarization state. The independent variable is usually the wavelength of
The monochromatic light that leaves the spectrometer is split into two beams before it enters the sample compartment. A spectrophotometer in which only one beam
The spectrometer uses a prism or a grating to spread the light into a spectrum. This allows astronomers to detect many of the chemical elements by their characteristic spectral lines.

Orthogonal extraction reflectron time-of-flight spectrometer OFT10, overall length ca. 900 mm, angle between in- and outgoing ion beam ca. 8°, field free drift length ca. 900 mm, two-stage ion reflector
It records an interferogram and uses a mathematical Fourier transform to produce an IR spectrum (absorbance or transmittance vs wavenumber, typically 4000–400 cm−1). ATR accessory is also
The slit only allows light of a very narrow range of wavelengths through into the rest of the spectrometer. By gradually rotating the diffraction grating, you can allow light from the whole spectrum (a tiny part
Despite the fact that quadrupoles produce the majority of mass spectra today as mentioned earlier, they are not true mass spectrometers. Actual mass spectrometers produce a distribution of ions either
A mass spectrometer has four essential elements: a means for introducing the sample to the instrument, a means for generating a mixture of ions, a means for
Experience FTIR beyond the ordinary with the Nicolet iS50 FTIR Spectrometer. User replaceable, room temperature. Compatible with standard. Filter wheel accepts up to five industry standard one inch
The second sphere is the 12 inch extended range sphere, made of an inner polyethylene sphere 6 diameter inches, a lead spherical shell 1 inch thickness and an external polyethylene shell
Selected area spectroscopy is performed by inserting an aperture into the electrostatic lens column, forming a virtual probe at the surface of the sample. Spectra are acquired from defined selected
In this paper, we present an optimized two-stage VIPA-based Brillouin spectrometer that achieves a contrast of at least 80 dB thanks to a single
Learn everything about optical spectroscopy and how to configure the right settings for optimal use for your usecase. Read more.
Typically, the slit of a grating spectrometer is rectangular instead of round. This is because the spectral resolution (= spot size along the wavelength axis of the IMAGE surface) is
In this paper we present a novel approach to the construction of a two stage VIPA spectrometer featuring only one VIPA etalon; thanks to a beam folding design that relies on two
In this paper, we present an optimized two-stage VIPA-based Brillouin spectrometer that achieves a contrast of at least 80 dB thanks to a single diffraction mask, and thus with an
The name ''mass spectrometry'' is a misnomer of sorts. The mass is not what is measured; instead, mass spectrometry determines the mass-to-charge (m/z) ratio or a property related to m/z.
