TE Cooled 1000-2500nm Near Infrared Fibre Optic Spectrometers



USB NIR spectrometer

New High Sensitivity Compact NIR Spectrometers in the EVO series! 

The new and improved versions of our NIR spectrometers offer more sensitivity, less weight and less size. They are based on a 100mm optical bench with a NA of 0.13 offering optimal balance between resolution and sensitivity.

The AvaSpec-NIR256 & 512-2.5-HSC-EVO series feature 256 or 512 pixel InGaAs detectors and are available in multiple configurations. These instruments are perfect for grain, corn, wheat, soya, and polymers  but also for medical uses, process monitoring and other analysis.


The 256 pixel detectors offer best sensitivity for most applications. But for applications where resolution is key, or more datapoints for modelling is required, the 512 pixel detector will be the best choice.

A range of gratings are available offering the possibility to tailor the instrument for optimal performance in your application. The instrument is also equipped with a replaceable slit which offers you great flexibility in your experiment.

Also available on the –HSC is the user selectable gain setting mode -  LN (low noise - standard setting), which gives you a longer integration time and higher signal to noise ratio, or HS (high sensitivity) for measuring in low light conditions.


Analog and digital IO ports enable external triggering and control of shuttered and pulsed light sources from the AvaLight series.


All EVO instruments including these NIR units use the AS7010 electronics board offering USB3 connectivity (10 times faster than USB2), Gigabit Ethernet and superior signal processing.
