Abstract
An analyzer for analyzing the surface of an object which is substantially opaque to ultraviolet light. The analyzer includes a substantially light-tight housing having an aperture therein for viewing the surface of the object to be analyzed. An illuminator is carried by the housing and includes a source of ultraviolet light and an optical imaging device for directing light from the source through the aperture and onto the surface of the object to illuminate the surface of the object. A collector is carried by the housing including a sensor responsive to ultraviolet light and an optical imaging device for receiving ultraviolet light from the surface through the aperture and directing it onto the sensor. A tilting mechanism is carried by the housing and permits relative tilting movement between the surface of the object and the housing whereby substantially only scattered energy is collected in one position of the housing and substantially only specularly reflected energy is collected in a second position of the housing.
