Ibsen’s spectrometers offer a range of fast detector options. Choosing the right detector for your application can be a challenge, so below we have gathered some of our best technical notes on detectors along with a few tips and tricks we believe would be helpful for your spectrometer projects when navigating through all the detector options.
Ibsen has a number of OEM spectrometer platforms available, that are well suited for integration into your LIBS analysis system. We offer the spectrometers with our DISB electronics, which give you the fast read-out and the precision control you need over your LIBS instrument. It is a match made in heaven.

DISB (Digital Image Sensor Board) is Ibsen’s own developed OEM ...
More...Laser Induced Breakdown Spectroscopy (LIBS) is an extremely versatile spectroscopic technique which can be used to analyze the atomic composition of virtually any material. In a LIBS system, a short laser pulse is used to ablate material from the surface of a sample. The laser pulse energy will be high enough to create bright plasma on the surface of the sample.
When choosing a spectrometer ...

A grating with high groove density has a high dispersion. This means that the angular separation of wavelengths from the grating is large. It can be desirable to choose a grating with high groove density for two main reasons:
However, there ...

This note describes how an existing spectrometer wavelength range can be scaled by changing the groove density of the transmission grating, without needing to change other aspects of the design. The starting point is a known spectrometer with a grating with groove density G0, detector width LD, and covering the wavelength range λmax,0 – λmin,0.
The focal length of this spectrometer is given by: ...
Absorbance spectroscopy is a molecular spectroscopy method that uses the wavelength dependent absorption characteristics of materials to identify and quantify specific substances.
Many molecules absorb ultraviolet or visible light emitted from a broadband light source. The absorbance is related to the concentration of the materials in the sample such that stronger absorbance means higher concentration.
There are many different approaches for measuring absorption spectra. ...
