Abstract
A specular variable angle absolute reflectometer. The device includes a light source and a mirror system in a light path of the light source. The mirror system is configured to reflect a light beam from the light source towards a sample that is optically reflective. The device also includes a roof mirror disposed in the light path after the sample. The roof mirror is configured to reflect the light beam back towards the sample. The device also includes a mechanism connected to the roof mirror. The mechanism is configured to rotate the roof mirror about an axis of the sample. The device also includes a detector in the light path after the roof mirror such that the detector receives light that has been reflected from the roof mirror, thence back to the sample, thence back to the mirror system, and thence to the detector.
