The V-750 is a high resolution UV-visible double-beam spectrophotometer with single monochromator, variable spectral bandwidth and a photomultiplier tube (PMT) detector
The optical design uses precision double-beam optics with variable spectral bandwidth. A high sensitivity PMT (photomultiplier tube) provides accurate and reproducible measurements for low to high concentration samples. By controlling the high voltage applied to the PMT, the dynode feedback offers a wider dynamic range. For high resolution measurements, such as gas and vapor phase spectroscopy the spectral bandwidth can be set as narrow as 0.1 nm. Special low stray light slit settings which optimize the light image on the monochromator provide increased linearity to up to 5 absorbance units.With a comprehensive range of sampling accessories, the V-750 is well suited to measurement of solid and liquid samples in the UV and visible regions, with temperature control for biological samples and a number of transmittance and reflectance accessories for materials analysis.
