AvaSpec-NIR256/512-1.7-EVO
For measurements in the near-infrared range up to 1.7 µm, Avantes offers a new series of uncooled spectrometer configurations. The AvaSpec-NIR256-1.7-EVO and the AvaSpec-NIR512-1.7-EVO offer the same high-sensitivity optical bench, but with the next generation of electronics. Both instruments deliver the same exceptional performance specifications, such as a sample speed of only 0.53 ms/scan and integration times as fast as 10 µs, as the Avantes instruments you have come to trust.
For applications where resolution is key, or more datapoints for modelling are required, the 512 pixel detector will be the best choice.
The AvaSpec-NIR256/512-1.7-EVO spectrometers pair the same trusted InGaAs array detectors with their ultra low-noise electronics board featuring USB3 and Giga-Ethernet connection port. Digital and analogue I/O ports enable external triggering and control over the shutter and pulsed light sources and choose from two distinct software-controlled gain-setting modes, high-sensitivity mode (HS, default) and the low-noise mode (LN).
These affordable, uncooled instruments are USB powered and are available with a choice of four gratings and replaceable slit options to match the bandwidth and requirements fitting your application.
Did you know the AvaSpec-NIR257-1.7 has a little brother? Avantes’ new AvaSpec-Mini-NIR uses the same detector as its bigger counterpart, but in a much smaller package. This makes it perfect for OEM use and integration into handheld devices.
