The NIRQuest512-1.9 offers a signal to noise ratio of >15000:1 at 100 millisecond integration time.
A high-resolution device with response from 1100-1900 nm, NIRQuest512-1.9 is well suited for applications ranging from monitoring changes in food production and chemical processing to characterising lasers for semiconductor assembly and medical treatment.
Features include:
- A high-stability, 512-element Hamamatsu Indium Gallium Arsenide (InGaAs)-array detector
- Multiple grating and optical bench options for optimising performance between 1100-1900 nm.
- External hardware triggering functions that allow users to capture data when an external event occurs
- Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform
- Signal to noise ratio at full signal is >15000:1 at 100 millisecond integration time.
The standard NIRQuest512-1.9 comes with a 150 lines/mm grating, 25 micron entrance slit and a non-fluorescing longpass filter that transmits >1000 nm. The filter helps to mitigate second-order effects.
The low dark noise characteristics of the NIRQuest make it possible to integrate the spectrometer (or expose the detector in the spectrometer to light) for longer durations, which is useful in low light level environments.
