Wavelength SeaWave 900 nm - 1700 nm

This extremely compact NIR spectrometer offers excellent performance and a user-friendly software interface. With no moving parts, this is a reliable device for integration in in-line and off-line analysers and for scientific applications.

A top of the range NIR spectrometer, showing the smallest footprint in the market for its class, the highest data acquisition speed (>1000spectra/second) and excellent resolution (3nm) for a broad detection range in the NIR (900 – 1700nm).

Based on Hamamatsu InGaAs linear array sensors, SeaWave® has no moving parts and hence it is a robust device which can be reliably used in OEM and scientific applications. Its small size and light weight make it an excellent spectrometer to be integrated in 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 fiber input connector to bring light into the device through an optical fiber and a slit which enables free space input coupling.

A USB 2.0 Hi-speed interface to connect it to a PC is available. Dlls and customised control software packages for specific requirements are provided.

Higher resolution (<3nm) is achieved at the expense of shorter detection ranges. Extended spectral ranges (>1700nm) are also available upon request.

A demo unit can be provided for testing the SeaWave®. Please get in touch with us for further information.
