Cost-Effective, Fully-Ingegrated Spectroradiometer with ISO17025 Accreditation

The ILT950-NIR compact air-cooled NIR spectrometer uses a 256 pixel linear InGaAs array, and offers both a high-sensitivity and low-noise mode for measurements in the near infrared range, out to 1700 nm (1.7 micron).  The ILT950-NIR allows for economical measurements by comparison to many TE cooled spectrometers, yet still offers exceptional performance.  With a sample speed of only 1.06 ms/scan, and integration times as fast as 10 µs, the ILT950-NIR offers fast, accurate results.


The ILT950-NIR can be combined with ILT's UV-VIS spectrometers by attaching a bifurcated fiber cable to both units, with only one shared input optic.  This allows for simultaneous, broad-spectrum measurements with minimal set up time.  Results are displayed for both systems in one graph, using ILT's easy-to-use SpectriLight software.
