摘要
The device is used to determine the roughness parameters of an object by comparing the specularly reflected light with the diffused light when the object is illuminated by a monochromatic incident beam. A system is provided which enables a rapid assessment to be made, either by reading or direct counting, of at least one roughness parameter. A head is provided into which the incident beam penetrates, the position of this beam being fixed. A reflected beam leaves the head, also with a feed position. The incident and reflected rays are parallel and the angle of incidence can have one of several prefixed values.
