Jasco V-530 UV/VIS Spectrophotometer w Control Software & LSE-701 Long Path Cell Holder

Web Information

The Jasco V-530 UV/VIS Spectrophotometer is designed to measure the absorption spectrum of a sample at wavelengths in the range 190 to 1100 nm. The light sources used in the V-530 are a deuterium(D2) lamp (190 to 350 nm) for the UV region and a halogen (WI) lamp (340 to 1100 nm) for the VIS/NIR region. The light from the light source is converged and enters the monochromator. The light is dispersed by the grating in the monochromator and converges onto the exit slit. The light that has passed through the exit slit is monochromated. This light is split into two beams, one going to the sample to be measured and the other to the reference sample such as a solvent. The light that has passed through the sample and the reference sample is alternately incident upon the silicon photodiode.
