Avantes offers three spectrometer configurations for measurements in the near infrared range out to 1.7 µm or 1700 nm.
The AvaSpec-NIR256-1.7 is the most cost-effective instrument in the NIR-range of spectrometers manufactured by Avantes, but offers outstanding performance specifications such as a sample speed of just 1.06 ms/scan and integration times as swift as 10 µs. This instrument is also available in RS-version which allows users to easily change the slit within seconds.
The AvaSpec-NIR256/512-1.7 TEC spectrometers are also affordable and can be operated in two different gain-setting modes - the low-noise (LN) mode and the high-sensitivity mode (HS, default). A software option enables setting of the different gain modes.
The NIR-1.7 instruments are available with a selection of four different gratings, making it possible to select the bandwidth matching a specific application. Analog and digital I/O ports enable external triggering and control over the shutter and pulsed light sources from the Avantes series of products. The uncooled AvaSpec-NIR256-1.7 is USB2 powered, but the TEC cooled instruments need external power.
