Spectrophotometers - SAGT557

Spectrophometers perform full spectrographic analysis of the color covering the whole wavelength in the visible, verifying the spectral curves and the metamerism. Two objects, equally illuminated, can have the same color with a given light source, but different color with another light source. Therefore, two objects of the same color, but produced at different times and with non-identical products, can reflect light in different ways. Spectrophotometer uses the principle of spectroscopy combination, that is to separate the light according to a certain wavelength interval. Spectrophometers are widely used in automotive, plastic, electronic, paint, ink, textile, fashion, printing, food, medical, cosmetic, scientific research institutes, schools and laboratories. The instrument is equipped with high-end color management software.
