ILT950 SPECTRORADIOMETER
ILT950 Spectroradiometer
The ILT950 has been retired. Please see the ILT960 replacement products at the links below
The ILT960 is a compact portable mini spectrometer used to measure both the lights amplitude and wavelength and provide calibrated spectral irradiance, radiance or power measurements. The ILT960 kits are combined with high end optics for proper light collection including diffusers for cosine correction, integrating spheres for total flux and radiance barrels for a narrow FOV. All ILT960 spectrometers include both wavelength and optical NIST traceable - ISO/IEC 17025:2017 Accredited calibrations with certification and data files. Complimentary SpectrILight III software is included at no cost and DLL’s are available upon request.

** (Note: Dual range calibration with D2 and QTH light source is strongly recommended for broadband measurements encompassing UV below 350 nm due to low output of the QTH lamp which increases the difficulty of accurate UV calibration. The ILT950 can be calibrated with QTH light source only if UVB/C accuracy is not consequential.)
