Near Infrared and Short Wave Infrared Spectroscopy

Featured Application on NIR and SWIR

Spectral diagnosis in the Near Infrared (NIR) or Short Wave Infrared (SWIR) is of key importance in scenarios involving for example deeper, non-invasive probing into biological samples, minimization of fluorescence in Raman-based biological samples analysis, investigation of increasingly popular NIR biotags including quantum dots or SERS tags, or characterisation of nanowires or carbon nanotubes.

Andor’s high sensitivity CCDs and InGaAs detectors and high throughput, high resolution spectrographs help Researchers on a day-to-day basis to overcome the photon collection challenges associated with these typically low light applications.
