NIR Spectrometers up to 1700nm (TEC Cooled)

NIR Spectrometers up to 1700nm (TEC Cooled)
 
||| |||

For measurements in the near infrared range out to 1.7 µm or 1700 nm, Avantes offers three spectrometer configurations. The AvaSpec-NIR256-1.7 is the most economical in the NIR-range of spectrometers made by Avantes, but offers exceptional performance specifications such as a sample speed of only 1.06 ms/scan and integration times as fast as 10 µs. This instrument is also available in RS-version meaning you can easily change the slit in a matter of seconds.

The AvaSpec-NIR256/512-1.7 TEC spectrometers are also affordably priced and can be operated in two distinct gain-setting modes, the high-sensitivity mode (HS, default) and the low-noise (LN) mode. Setting of the different gain modes can be done via a software option. All NIR-1.7 instruments are available with a choice of four different gratings, making it possible to choose the bandwidth fitting your application. Digital and analog I/O ports enable external triggering and control over the shutter and pulsed light sources from the Avantes line of products. The uncooled AvaSpec-NIR256-1.7 is USB2 powered, while the TEC cooled instruments require external power.
