The Seawave from Radiantis is a near infrared spectrometer with no moving parts, small footprint, a data acquisition speed of >1000 spectra/second and resolution of 3 nm for a broad detection range in the IR (900–1700 nm). It is based on Hamamatsu InGaAs linear array sensors, and its small size and light weight make it suitable for integration into in-line and off-line analysers for the food and pharmaceutical industry, as well as handheld analysers for routine process testing. It features a versatile entrance aperture which incorporates both a standard fibre input connector to bring light into the device through an optical fibre and a slit which enables free space input coupling. A USB 2.0 interface connects it to a PC, and DLLs and customised control software packages for specific requirements are provided. The higher resolution (<3 nm) is achieved at the expense of shorter detection ranges; extended spectral ranges (>1700 nm) are also available upon request.
