Compact, Tunable, NIR Spectrometer

The SM302 is a versatile, high performance, compact InGaAs array spectrometer that consists of a low noise, 256-element, InGaAs array detection module, a high precision tunable spectrograph optimized for the spectral range of 0.9 to 1.7µm (0.9 to 2.6µm extended), a 16-bit data acquisition board, and Windows® based operating software.

The dual grating capacity spectrometer comes preloaded with one grating and slit tailored for high-resolution work throughout the usable range of the detector. An optional second grating may be loaded to add wide coverage capability, or both gratings may be user specified to achieve desired coverage and resolution. Integrated filters allow the user to selectively block out unwanted higher orders, and the standard dual function entrance can accept light directly coupled through the built-in slit or from a standard NIR fiber.

The SM302 detector is a multiplexed InGaAs array that is thermoelectrically cooled and temperature stabilized to ensure long-term operation stability. The multichannel detection with a readout rate of 333 kHz or faster both reduces measurement time and enhances signal-to-noise ratio.
