The CS-2000 is Konica Minolta‘s portable spectroradiometer. Used for precise measurement of electromagnetic radiation in the visible spectrum. A high resolution photodiode cell accurately captures 380 nm to 780 nm at 0.9 nm wavelength intervals. An electrically-cooled sensor and time current measurements, optimise the signal to noise relationship which leads to an excellent repeatability and measurement accuracy even at low luminance levels of 0.003 cd/m². The polarisation error is minimized to below 2% by a special light wave conductor optic inside the CS-2000.
