Since spectroscopy is used for numerous applications. We have defined our products in different lines, as seen below. We offer instruments with a small form factor to integrate into other devices in the CompactLine: high-sensitivity instruments for more demanding applications in the SensLine and spectrometers especially configured for the near-infrared range in our NIRLine. The StarLine spectrometers are our most versatile instruments for general spectroscopy applications.

What is spectroscopy?

Optical spectroscopy is a technique for measuring light intensity in the ultraviolet, visible, near-infrared and infrared wavelength ranges. It is the study of the absorption and emission of light and other radiation by matter. It is also the study of interactions between particles such as electrons, protons and ions. Spectroscopic measurements are being used in many different applications, such as color measurements, concentration determination of chemical components or electromagnetic radiation analyses. 

What is a spectrometer?

A spectrometer is an instrument that is used to measure the variation of a physical characteristic over a given range. There are different types of spectrometers. The most common spectrometers are mass spectrometers, NMR spectrometers and optical spectrometers.

What does a spectrometer measure?

Spectrometers measure the frequency emitted by the substance being analyzed. To further understand this, it is good to know that the method is called spectroscopy. This means that we can define spectrometry as quantifying the amount of energy absorbed by matter and the light that it creates in the process. Each substance will either transmit or absorb light basically. The frequency by which the substance does this identifies what substance it is. 

How does a spectrometer work?

There are many different types of spectrometers to pick from. The type of spectrometer depends on the needed measurement technique for your application. Avantes specialises in high-end fibre-optic spectroscopy systems which facilitate measurements in the ultra-violet, visible and near-infrared wavelength.

What is a spectrometer used for?

Spectroscopic techniques have been applied in virtually all technical fields of science and technology. For example; spectroscopy is used in chemistry through measuring a great variety of chemical reactions and to deeply understand how these reactions take place. Spectrometers are also well used within the scientific community. For example; within the study of the interactions between particles such as electrons, protons, and ions, as well as their interaction with other particles as a function of their collision energy. Another field where spectroscopy is widely used is within the biomedical industry. A known medical technique is called magnetic resonance imaging, otherwise known as MRI to visualize the internal soft tissue of the body with unprecedented resolution.

What is the function of a spectrometer?

To further explain the function of a spectrometer it is best to read about the different applications. We can divide the applications of spectroscopy into the following categories;
