Request InfoAvantes BVAvantes BV has unveiled the AvaSpec-NIR256 spectrometer, available with two InGaAs detector types — an uncooled version for applications up to 1.7 μm and a two-stage Peltier-cooled extended version, covering a range of up to 2.2 μm. The device has 256 pixels and can be combined with all of the company’s other AvaSpec-USB2.0 spectrometers in the UV/VIS range to form a multichannel system that covers the 200-nm to 2.2-μm range. It uses a 50-mm-focal-length f/2 optical bench for high sensitivity. A choice of NIR-blazed gratings is available.
