AvaSpec-Mini-NIR
Small and Powerful OEM NIR Spectrometer
AvaSpec-Mini-NIR256-1.7

The latest addition to our CompactLine: theAvaSpec-Mini-NIR!
The AvaSpec-Mini-NIR is a compact
near-infrared spectrometer, based on a
combination of our popular AvaSpecNIR256-1.7 and Mini-series.
This NIR spectrometer might not be as
sensitive as our bigger NIR spectrometers,
but this loss in sensitivity is greatlycompensated by its size and robustness.

and USB powered, which makes it easy tointegrate into other devices, including butnot limited to OEM handheld applications.
This versatile miniature near-infrared
spectrometer is well suited for various
applications, including food analysis and therecycling industry.
Of course, the AvaSpec-Mini-NIR works
seamlessly with our AvaSoft software andthe Windows and Linux libraries we haveavailable.

Like our other CompactLine spectrometers,
this device is only the size of a deck of cards

AvaSpec-NIR256/512-1.7-EVO
NIRLine Near-Infrared Fiber-optic Spectrometer
For measurements in the near infrared rangeout to 1.7 µm, Avantes offers a new series ofuncooled spectrometer configurations. The
AvaSpec-NIR256-1.7-EVO and the AvaSpecNIR512-1.7-EVO offer the same high sensitivity optical bench with the next generationof electronics. Both instruments deliver thesame exceptional performance specifications such as a sample speed of only 0.53
ms/scan and integration times as fast as 20µs, as the Avantes instruments you havecome to trust.
For applications where resolution is key, or
more datapoints for modelling is required,the 512 pixel detector will be the bestchoice.

The AvaSpec-NIR256/512-1.7-EVO spectrometers pair the same trusted InGaAs array
detectors with our ultra low-noise electronics board featuring USB3 and Giga-Ethernet
connection port. Digital and analog I/O
ports enable external triggering and control
over the shutter and pulsed lightsources
and choose from two distinct software-controlled gain-setting modes, high-sensitivity
mode (HS, default) and the low-noise (LN)mode.

AvaSpec-NIR256/512-2.5-HSC-EVO
NIRLine Near-infrared Fiber Optic Spectrometer
AvaSpec-NIR256-2.5-HSC-EVO

The new and improved versions of our NIR
spectrometers offer more sensitivity, lessweight and less size. They are based on a100mm optical bench with a NA of 0.13 offering optimal balance between resolution andsensitivity.
The 2.5-HSC series feature 256 or 512 pixel
InGaAs detectors and are available in multiple
configurations. These instruments are perfectfor grain, corn, wheat, soya, polymers but also
for medical uses, process monitoring and otheranalysis. The 256 pixel detectors offer best sensitivity for most applications.

Also available on the –HSC is the userselectable 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 lowlight
conditions. Analog and digital IO ports enable
external triggering and control of shutteredand pulsed light sources from the AvaLight
series.
The EVO instruments use the AS7010 electronics board offer­ing USB3 (10 times faster thanUSB2), Gigabit Ethernet and better signal pro­cessing.

For applications where resolution is key, or
more datapoints for modelling is required, the512 pixel detector will be the best choice.
