The AvaSpec-NIR256/512-2.0/2.2/2.5 Fiber Optic Spectrometers are based on the AvaBench-50 symmetrical Czerny-Turner design with 256 and 512 (2.2 model only) pixel TE Cooled extended InGaAs Detector Arrays. The spectrometer has a fiber optic entrance connector (standard SMA, other connectors also available), collimating and focusing mirror and diffractional grating. A choice of 4 gratings with different dispersion and blaze angles enables measurements in the 900-2500nm range.
The AvaSpec-NIR256-2.0/2.2/2.5 instruments include a 16 bit AD converter, and USB2.0 high speed interface. The AvaSpec- NIR256/512-2.0/2.2/2.5 have a 2-stage Thermo-electrical Peltier-cooled InGaAs detector, designed for measuring in the NIR range from 1000-2000/2200/2500nm. The AvaSpec-NIR256-2.0 has a very low dark noise level enabling longer integration times for low light level applications. Analog and Digital IO ports enable external triggering and control of shuttered and pulsed light sources from the Avantes line of instruments. The AvaSpec-NIR256/512 series instruments have a USB2 interface with fast data sampling of almost 2000 spectra per second and data transfer in 1.0 ms. All instruments in this line are also available with optional Bluetooth (-BT) communication and/or an SD card for on-board storage of spectra. The AvaSpec-NIR-256/512-2.0/2.2/2.5 come in a our new vertical housing and run on 100-240VAC. All instruments come with AvaSoft-basic, a complete manual and USB interface cable. Multiple USB2 spectrometers with different detector types can be externally coupled.
