  USP-4000 Spectroradiometer select Japanese HAMAMATSU high sensitive array sensor with 2048 pixels and choose high precision grating and hitchhiked Cerny - Tuener optical platform. It can restrain the stray light is very good, to achieve high sensitivity, high dynamic range, high speed measuring, measuring time can reach microsecond. 16-bits AD programmable modules are used to design the circuit, synchronous clock driver curbs CCD reset noise effectively, programmable controlled bias voltage acquires large dynamic testing range, and then data transmitted from high-speed USB2.0 interface to PCs.  Spectroradiometer is widely used to measure the spectral, photometric and colorimetric parameters of all kinds of lighting sources which include relative spectral power distribution P(λ), chromaticity coordinate (x,y), (u,v), corrected color temperature Tc, color rendering index Ra, dominant wavelength, peak wavelength, spectral bandwidth, color purity, color ratio, SDCM, luminous flux, Illuminance, luminance, spectral transmittance and reflectance, etc.
