The new and improved versions of our NIR spectrometers offer higher sensitivity, lower weight, and a smaller size. They are based on a 100mm optical bench with an NA of 0.13, offering optimum balance between resolution and sensitivity.
The 2.5-HSC-EVO series feature 256 or 512 pixel InGaAs detectors and are available in multiple configurations. These instruments are perfect for grain, corn, wheat, soya, and polymer measurements but also for medical uses, process monitoring, and other analyses. The 256-pixel detectors offer the highest level of sensitivity for most applications. For applications where resolution is key, or more data points for modelling are required, the 512-pixel detector will be the best choice.
A range of gratings are available, making it possible to tailor the instrument for optimum performance in your application. The instrument is equipped with a replaceable slit, which offers you great flexibility in your experiment.
Also available on the –HSC is the user-selectable gain setting mode: LN (low- noise, standard setting), which gives you a longer integration time and higher signal-to-noise ratio, or HS (high sensitivity) for measuring in low light conditions. Analogue and digital IO ports enable external triggering and control of shuttered and pulsed light sources from the AvaLight series. The EVO instruments use the AS7010 electronics board, offering USB3 (10 times faster than USB2), Gigabit Ethernet and better signal processing.
