DIGITAL FIBER SPECTROMETER
(USB3000-ILX511) 

USB3000 is applicable for spectral detection within the wavelength range between 200nm and 1100nm. Because of the high stability and high performance, these portable instruments can greatly satisfy the increasing need for scientific research, industrial manufacture, online detections and so on. USB3000 is capable of measuring Spectral power distribution, Absorbance, transmission, reflection, Relative irradiance, Chromaticity coordinates, Color temperature, Color rendering index, Color tolerance, Color difference, Color purity, Main wavelength, Luminous flux, Luminance, Irradiance power and Luminous effciency .etc of various kinds of samples, light sources and display devices. Besides they can also be utilized to achieve photochromic analysis of Florescence lamps, High pressure gas discharge light sources, Halogen-tungsten lamps, medical light sources, Semi-conductor lighting devices and Display devices as CRT, LCD, PDP, ELD, VFD. USB3000 can offer the optimal solutions for spectral detections. With different system configurations and sampling accessories, USB3000 can achieve high spectral resolution up to 0.2nm, stable wide, narrow and line spectrums with different optical interfaces. Furthermore, with the easy-to-use basic operating software and high effcient SDK, end users could easily achieve various kinds of spectral dectection systems to meet their own goals.
