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.
