AvaSpec-NIR256/512-1.7-HSC-EVO
For measurements in the near-infrared range up to 1.7 µm, Avantes offers a new series of cooled spectrometer configurations. The AvaSpec-NIR256-1.7-HSC-EVO and the AvaSpec-NIR512-1.7-HSC-EVO offer the high-sensitivity 100mm optical bench (HSC) with the next generation of electronics (EVO).
Both instruments deliver exceptional performance specifications such as a high sample speed and integration times as fast as 20 μs, as the Avantes instruments you have come to trust. For applications where resolution is key, or more datapoints for modelling is required, the 512 pixel detector will be the best choice.
The AvaSpec-NIR256/512-1.7-HSC-EVO spectrometers pair the same trusted InGaAs array detectors with Avantes’ ultra-low-noise electronics board, featuring a USB3 and Giga-Ethernet connection port. The instruments are equipped with a Replaceable Slit. Digital and analogue I/O ports enable external triggering and control over the shutter and pulsed light sources. Choose from two distinct software-controlled gain-setting modes: high-sensitivity mode (HS, default) and low-noise mode (LN).
Cooling ensures optimum noise conditions, even at longer integration times. All NIR-1.7 instruments are available with a choice of four different gratings, making it possible to choose the bandwidth fitting your application.
