ILT 900 Wideband Spectroradiometer

Powerful, economical digital light meter easily and accurately measures spectral irradiance from the UV to the infrared (near), lux, color, and more. Precision, portable USB powered spectrum measurement instrument.
The most cost-effective, fully integrated CCD-based spectroradiometer family available.

Aimed at both the laboratory and industrial user, the ILT900 combines accuracy, ruggedness and complete user control in a package designed specifically for radiometric use. Measure wavelength, measure color, measure reflectance or transmittance this portable, digital light meter puts the power in your hand. Even the basic ILT900-R instrument includes everything needed for the widest range of standard measurements and has a large range  of specialized accessories to suit the most unusual requirements. Complete with input optics, software, cables, manuals and complete calibration, the ILT900 is ready to work right out of the box.

SpectriLight III Screenshot

The NEW version of SpectriLight™ III provides easy setting of all operating controls of the ILT900 spectrometer with an integrated data analysis package (previously an Excel™ export module called SpectriLight™Tools). The analysis package will make your spectral analysis fast and simple. Wavelength range, integration time, scan average and other controls can be easily set through pop up windows, menus and toolbars. The analysis screens provide detailed analysis of the calibrated data. Absolute Irradiance and chromaticity are calculated instantly.

SpectriLight™ III comes standard with our ILT900 Portable Spectroradiometer familiy - The most cost-effective, fully integrated CCD-based spectroradiometer family available - and is available as an upgrade for all exisiting  ILT900 users with Spectrilight/Spectrilight Tools software.

The user interface of SpectriLight™ III is very powerful and easy to use minimizing the learning curve to operate the ILT900 spectrometer. SpectriLight™ III is LabView™ based software and can be easily customized for specific OEM applications. For API applications, a DLL is available. Please contact our applications specialists who will work with you to create a package tailored to your needs
