The ILT950 spectroradiometer from LOT Quantum Design has had a machined optical bench added for reduced stray light and improved thermal stability. Also a new CCD array results in more sensitivity over the entire spectral region.

Specifications include: 200-450nm spectral range; 1nm resolution (50µm slit); dual calibration for higher accuracy (deuterium and QTH), and USB powered.

Typical applications include characterisation of solar simulation and LED illumination and colour analysis.
