Ocean Optics Inc. has increased the capabilities of its compact near-infrared spectrometers with the NIRQuest512-2.5. A high-resolution device with response from 900 to 2500 nm, it is suitable for laser characterization and applications requiring longer integration times. The company says that the instrument extends the wavelength range without sacrificing optical resolution. A high-stability, 512-element Hamamatsu InGaAs array detector doubles the amount of pixels previously available in the 900- to 2500-nm range, increasing optical resolution. Depending on the user-selected configuration of grating options and optical bench entrance slit size, optical resolution of 4.1 to 6.3 nm FWHM is possible. The lower overall dark noise of the system enables the longer integration times, which is useful in low-light-level environments.
