The V-750 UV-Visible Spectrophotometer optical design uses precision double-beam optics with variable spectral bandwidth. A high sensitivity PMT detector provides accurate and reproducible measurements for low to high concentration samples. The dynode feedback offers a wider dynamic range than is generally found on UV-Visible spectrophotometers. 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. The automatic 6-position Peltier cell changer allows for temperature controlled measurments.For further details or assistance, please feel free to contact us.
