Array Spectrometer, SM301

The SM301 is a versatile, high performance PbS/PbSe array spectrometer. Its active components include a TE cooler and a 256-element PbS detector element array. Operation of the unit for research applications. The system is ideal for spectroscopic applications in the 1.0 to 3.0 micron (PbS) region.

 The SM301 includes thermoelectric cooling to guarantee long-term operational stability. The SM301 employs a multiplexed PbS array as its NIR detection element. The array is cooled and temperature stabilized at around -10°C which ensures long-term operation stability. Dark signal can thus be automatically measured by the built-in electronics periodically and subtracted automatically. Compared with conventional scanning NIR spectrometers the SM301 provides the multi-channel detection advantage, both in reducing the measurement time and enhancing measurement signal-to-noise ratio. The SM301 can operate at a readout rate of 2MHz or faster allowing fast measurement and averaging operation to be performed in a short period of time.
