The AvaSpec-NIR256/512-1.7 Fiber Optic Spectrometers are based on the AvaBench-50 symmetrical Czerny-Turner design. The AvaSpec-NIR256-1.7 has a 256 pixel uncooled InGaAs Detector Array and the new AvaSpec-NIR256/512-TEC instruments feature 256/512 TE cooled NIR detectors. 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 enable measurements in the 900-1750nm range.
The AvaSpec-NIR-1.7 instruments include a 16 bit AD converter, and USB2.0 high speed interface. The AvaSpec-NIR256-1.7 series are especially suitable for measurements in the NIR, such as plastics classification and detection/quantification of water. Analog and Digital IO ports enable external triggering and control of shuttered and pulsed light sources from the Avantes line of instruments. The AvaSpec-NIR256/512-1.7 series instruments have a USB2 interface with fast data sampling of up to 940 spectra per second and data transfer down to 1.56 ms. All instruments in this line are also available with optional BluetoothÒ (-BT) communication and an SD card for on-board storage of spectra. The AvaSpec-NIR-256-1.7 runs on USB power, the TEC models come in our new vertical housing (see picture) and run on an external 100-240VAC power supply. All instruments come with AvaSoft-basic, a complete manual and USB interface cable. Multiple USB2 spectrometers with different detector types can be externally coupled (see section multi-channel spectrometers).
