UV-1800F Ultraviolet Transmittance Analyzer

Fast

The UV-1800F rapidly measures the diffuse transmittance of textilesamples in the ultraviolet wavelengthregion from 250 - 450 nm. Labsphere’s Spectralon integrating sphere incorporates areoptimized xenon flash lamp to provide exceptional diffuse illumination of the product sample and minimize data integration time. New high performance diode array spectrometers coupled by new advanced fiber optics are optimized at the system level for low stray light with superior wavelength stability and flash-to-flash repeatability.
