    摘要: Disclosed is a triangular shaped retarder system, for entering retardation between orthogonal components of an electromagnetic beam of radiation. The triangular shaped element, as viewed in side elevation, has first and second sides which project to the left and right and downward from an upper point. A third side is oriented essentially horizontally and is continuous with, and present below, the first and second sides. During use in a spectroscopic ellipsometer/polarimeter system, an entered beam of electromagnetic radiation exits in a propagation direction which is essentially undeviated and undisplaced from the direction of its incidence, even when the retarder system is caused to rotate about the locus of the beam of electromagnetic radiation.

    摘要: A retarder system and method of its use in ellipsometers and polarimeters are disclosed. The retarder system is a parallelogram shaped element which, as viewed in side elevation, has top and bottom sides which are parallel to one another. The retarder system also has right and left sides which are parallel to one another, with both the right and left sides being oriented at an angle to the top and bottom sides. The retarder system is made of a material with an index of refraction greater than that of a surrounding ambient. In use an input beam of electromagnetic radiation is caused to enter the right or left side of the retarder system, is diffracted inside the retarder system, and follows a locus which causes it to essentially totally internally reflect from internal interfaces of both the top and bottom sides, then emerge from the retarder system at the opposite, left or right respectively, side in a direction which is essentially undeviated and undisplaced from the locus of the input beam of electromagnetic radiation, even when the retarder system is caused to rotate about an axis coincident with the locus of the electromagentic beam.

    摘要: Disclosed are retarder systems, for entering retardation between orthogonal components of an electromagnetic beam of radiation, having first and second Berek-type retarders which each present with first and second essentially parallel sides. The first and second Berek-type retarders are oriented, as viewed in side elevation, with first and second sides of one Berek-type retarder being oriented other than parallel to first and second sides of the other Berek-type retarder. During use in a spectroscopic ellipsometer/polarimeter system, a beam of electromagnetic radiation exits in a propagation direction which is essentially undeviated and undisplaced from the direction of an incident beam of electromagnetic radiation, even when the retarder system is caused to rotate about the locus of the beam of electromagnetic radiation. A system with similarly oriented third and fourth Berek-type retarders, sequentially placed after the first and second Berek-type retarders, is also disclosed.
