FAQs About Portable Spectrophotometers
Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.
D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.
