AvaSpec-NIR256 Fiber Optic Spectrometer 900-2500 nm
The AvaSpec-NIR256 Fiber Optic Spectrometers is based on the AvaBench-50 symmetrical Czerny-Turner design with 256 pixel InGaAs Detector Array. The spectrometer has a fiber optic entrance connector (standard SMA, others possible), collimating and focusing mirror and diffractional grating. A choice of 3 gratings with different dispersion and blaze angles enable applications in the 900-2500nm range. The AvaSpec-NIR256 includes a 16 bit AD converter, and USB2.0 high speed interface. The AvaSpec- NIR256-1.7 is especially suitable for measuring in the NIR range from 900-1750nm applications, e.g. plastics and water absorbance. The AvaSpec- NIR256-2.2/2.5 have a 2-stage Thermo-electrical Peltier-cooled InGaAs detector, specially suitable for measuring in the NIR range from 1000-2200/2500nm.
Digital IO ports enable external triggering and control of shutter and pulsed light sources from the Avantes line of instruments.
The new AvaSpec-NIR256 series have a USB2 interface with fast datasampling of 940 spectra per second and datatransfer in 1.56 msec and supports analog in-and outputs as well. Optional Bluetooth® (-BT) communication and an SD card for on-board saving of spectra can be added. The AvaSpec-NIR-256-1.7 runs on USB power, the AvaSpec-NIR-256-2.2/2.5 comes in a desktop housing and runs on 100-240VAC. Both come with AvaSoft-basic, a complete manual and USB interface cable. Multiple (up to 127) USB2 spectrometers with different detector types can be externally coupled(see section multi-channel spectrometers).
