When you are considering to buy a new spectrometer, you may have to decide whether you need one with a cooled detector or not. A cooled detector can provide low noise but is also bulky and expensive. We have put together a technical note with some practical guidelines on when to cool and when not to cool. One of the applications where cooling is often required is in Raman spectroscopy. In this newsletter, we are highlighting our high throughput, compact EAGLE SW-NIR spectrometer which is well suited for Raman and comes both with a cooled and a non-cooled detector.
