International Light ILT950 Spectroradiometer

Portable Spectroradiometer

The excellent performance of the ILT950 Spectroradiometer has been improved with the addition of a new technologically advanced CMOS sensor. The new detector offers a more balanced overall spectral sensitivity (consistent in UV and lower in VIS and NIR), faster response times, faster data transfer rates and lower integration (as low as 30 μs) to allow measurement of higher signals without saturation.

The ILT950 comes in three models covering 250-1050 nm, UV 200-450 nm, and NIR 900-1750 nm; a broadband 250-1750 nm system can be created by coupling units. ILT systems come complete with fibre optics, input optics, calibration and ILT’s powerful SpectrILight III software.


SpectrILight™ III is a LabView™ based software package for Windows that allows you to acquire spectral and color data. Analysis of the data is now calculated instantly within the same program – no exporting required!

The NEW version of SpectrILight™ III has additional calculations for metamerism, and 2 and 20 degree observer. The new Overlay feature allows the user to compare the base reading to current readings. Wavelength range, integration time, scan average and other controls can be easily set through pop up windows, menus and tool bars. Absolute irradiance and chromaticity are calculated instantly

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 fibre 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.
