Yes. The LED light source has fixed colour and is not used to calculate colour values. These are calculated using standardised illumination functions stored on the instrument. The LEDs illuminate the sample in the electromagnetic wavelength range between 400 to 700 nm. The amount of light absorbed in this range at the different wavelengths is measured. The great advantage of using polychromatic white and blue LEDs to illuminate the samples is that they are practically indestructible. The light intensity stays constant for the lifetime of the instrument, which guaranties a very good long-time stability of results. Time consuming and costly lamp replacement is not needed!
