PerkinElmer* Lambda* 800/900 and 10/20/40 Accessory - Each

For relative specular reflectance studies which require data from more than one angle of incidence, the variable angle accessory is ideal. The angular range is from 15 to 70 degrees with an accuracy of +/- 1 degree. Typical applications include the study of how the reflectivity of a sample changes with change of incident angle.
