Abstract. Two optical-mechanical installations realizing the fast variation of angle of laser beam incidence upon a steady sample surface with subsequent registration of reflected beam intensity are described. Application of spherical lenses or mirrors instead of the elliptic ones lowers the device cost significantly.
Keywords: incidence angle, laser interferometry, thin films.
