The Choice for Low Signal Level NIR Applications

Spectral Products is offering the new SM304 TE cooled InGaAs array spectrometers.

The SM304 series are ideal for NIR spectrometry that requires very high signal to noise ratio and/or high dynamic rang. The high performance with low-noise level of the SM304 series makes it possible to apply in very demanding applications.

The good sensitivity of the detectors used in the SM304 series allows various broad-band applications like, measuring optical properties of various samples in NIR range, analyzing chemicals/moisture detection, as well as a narrow band applications like NIR laser characterization.

Standard interface to the SM304 series is a USB 1.1/2.0 compatible interface with 16-bit. Software support includes a SDK and DLLs for dedicated applications development and our SM32Pro Windows-based spectral acquisition and analysis software.
