  This blog features our extremely popular FREEDOM series of spectrometers using the latest CMOS detector technology. This combination of spectrometer and detector enables us to deliver highly sensitive and fast spectrometers with high resolution and low stray light in a very compact form factor. Spectrometer FREEDOM 101 The FREEDOM 101 spectrometers provide sensitivity, accuracy, and speed that you have previously only been able to obtain with expensive CCD detectors. This is accomplished through the use of a new CMOS technology that offers roughly the same sensitivity as CCD sensors. Our FREEDOM spectrometers combine compact size with high performance in terms of high resolution and low

You probably from time to time need to do some quick evaluation of various optical designs for a spectroscopic system. And you don't want to spend days running a full numerical calculation tool like Zemax or CODES. Very often, you need to cover a specific wavelength range with a certain resolution and want to evaluate how different detector widths, grating groove densities, and image magnifications will affect your focal lengths and slit sizes. To do that, we have created a handful of guides and calculators that we ourselves find very useful. These include: Spectrometer design technical note Detector selection guide Spectrometer design

  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. Quantum Efficiency in Detectors  The sensitivity of different detectors is not always reported equally in datasheets. Some use sensitivity in A/W, others may report a sensitivity of V/(lx s), and finally some report it as quantum efficiency. This makes it difficult to perform direct comparisons and to

  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 Spectrometer Electronics with Fast Timing for Instrument Integrators DISB (Digital Image Sensor Board) is Ibsen’s fast and accurate OEM spectrometer electronics. It comes with an SPI interface, which makes it ideal for fast and easy integration into your instrument. DISB furthermore offers fast readout – up to 600 Hz for 2048 pixels – and
