Spectral Products offers the new SM304 TE-cooled InGaAs array spectrometers. The SM304 series is ideal for NIR/SWIR spectrometry requiring a very high signal-to-noise ratio and/or dynamic range. The low noise and high performance of the SM304 series allow for a wide range of demanding applications. The good sensitivity of the detectors used in the SM304 series allows various broad-band applications like measuring the optical properties of diverse samples in the NIR/SWIR range, analyzing chemicals/moisture detection, and narrow-band applications like NIR/SWIR laser characterization. The standard interface to the SM304 series is a USB 1.1/2.0 compatible interface with 16-bit. Software support includes an SDK and DLLs for dedicated applications development and our SM32Pro Windows-based spectral acquisition and analysis software. The newly upgraded SM304 features an auto-shutter function for automatic dark conditions. Users don't need to block any input light to set 0% transmission (dark scan).
