UltraScan VIS Features
The UltraScan VIS is a dual beam xenon flash spectrophotometer with a wavelength range from 360 to
780 nanometers (nm). All tristimulus integrations are based on a triangular bandpass of ten nm and a
wavelength interval of ten nanometers. The instrument can measure both reflected and transmitted
color of a product.
The sensor uses a plastic integrating sphere that is six inches (152.4 mm) in diameter and coated with
Spectraflect™, which diffuses the light from the lamp. The light illuminates the sample and is either
reflected from it or transmitted through it. A lens is located at an angle of 8° from the perpendicular to
the sample surface. The lens collects the reflected or transmitted light and directs it to a diffraction
grating which separates the light into its component wavelengths. These components are then
measured by dual diode arrays and converted into usable data.
