AvaSpec-Mini NIR: InGaAs Inside
Avantes is excited to expand the range of NIR spectrometers to the AvaSpec-Mini platform. A 256 element InGaAs detector covers 900-1750nm with resolution down to 2nm. Like the original AvaSpec-Mini, the NIR series is only the size of a deck of cards, though with excellent temperature and wavelength stability. This instrument is easy to take anywhere you like, and is very well suited for OEM and handheld applications.
InGaAs inside
The AvaSpec-Mini-NIR is equipped with a 256 pixel InGaAs detector array covering the spectral range from 900-1750nm. With no moving parts, USB powered and compact size, it is ideal for OEM and handheld applications. With low stray light and resolution as good as 2nm, nothing comes close to offering this performance in such a compact package. Both high sensitivity (HS) and low noise (LN) amplifiers
