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.
