Ocean Optics has added another option to its small-footprint near-infrared spectrometer line with the NIRQuest512-1.9.

A high-resolution device with response from 1100-1900nm, 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. NIRQuest512-1.9 has a high-stability, 512-element Hamamatsu Indium Gallium Arsenide-array detector and is available with multiple grating and optical bench options for optimising performance between 1100-1900 nm. The standard NIRQuest512-1.9 comes with a 150 lines/mm grating, 25micron entrance slit and a non-fluorescing long pass filter that transmits >1000nm. The filter helps to mitigate second-order effects.
