The ILT950 is equally at home on the production floor as it is the laboratory, combining high performance, accuracy, ease-of-use, and a wide array of features all in a rugged, compact, portable design. The excellent performance of the ILT950 has been improved even further with the addition of a new CMOS detector allowing for faster response and data transfer rates as well as a more balanced overall spectral sensitivity, and integration times as brief as 30 µseconds.

The new CMOS sensor, combined with ILT's powerful SpectrILight III software, including PAR µmol/m²/s, Metamerism, and baseline overlay comparisons, make the ILT950 a top performer in the CCD array spectroradiometer market.

** (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.)
