Description | The V-760 UV-Visible Spectrophotometer includes a double monochromator for exceptional resolution with extremely low stray light (0.00008 %) for more accurate measurement over the widest photometric range (up to 8AU). The V-760 provides excellent sensitivity for diffuse reflectance or transmittance The V-760 UV-Visible Spectrophotometer includes a double monochromator for exceptional resolution with extremely low stray light (0.00008 %) for more accurate measurement over the widest photometric range (up to 8AU). The V-760 provides excellent sensitivity for diffuse reflectance or transmittance of solid and liquid samples using an integrating sphere. For high resolution measurements, such as gas and vapor phase spectroscopy, the spectral bandwidth can be set as narrow as 0.1 nm. Extended photometric linearity up to 8 Abs enables measurement of highly absorbing samples and is also useful for measurements of optical material with transmission characteristics that approach 0% T....

A high sensitivity PMT detector provides accurate and reproducible measurements for low to high concentration samples. By controlling the high voltage applied to the PMT, the 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. By controlling the high voltage applied to the PMT, 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....
