16 Apr 2007 For applications in the Near Infrared range, from 1000 nm to 2.5 µm, we have the AvaSpec-NIR256-2.5. Available with 3 different InGaAs detectors: non-cooled for applications up to 1.7 µm, and 2 with 2 stage programmable cooling for 2.2 µm and 2.5 µm. The AvaSpec-NIR256 has 256 pixels and can be combined with all other AvaSpec-USB2 spectrometers to cover the entire UV, VIS, and NIR range from 200 nm to 2.5 µm. It uses a 50 mm focal length optical bench with an F-number of 2 to maximize sensitivity. Different NIR blazed gratings are available. |
