Ocean Optics (Dunedin, Florida) has enhanced the NIRQuest series of small-footprint near-infrared spectrometers. All NIRQuest spectrometer models now come with a replaceable slit design as standard, increasing measurement flexibility with easy user changes in the field. Additionally, the option of adding an internal shutter is now available to more effectively manage light throughput and dark measurements in experiment setups.

The NIRQuest is a robust, reliable spectrometer with a fast response time and good optical resolution over 900- 2500 nm to suit applications from moisture detection and chemical analysis to high-resolution laser and optical fiber characterization. Slit size is one of the determining factors in the optical resolution of a spectrometer. A larger slit increases throughput, but at the expense of optical resolution. A smaller slit yields higher optical resolution, but decreases throughput. The flexibility to adjust the width of the slit helps eliminate trade-offs.
