<p>In accordance with the invention, an improved optical assembly (200) having a monolithic structure, and an improved optical assembly having a monolithic structure and a retroreflector/beamsplitter combination is provided. The monolithic optical assembly comprises top (260) and bottom (270) plates which are joined into a monolithic structure by first (210) and second (220) mounting members and a beamsplitter (130). The assembly also comprises a first reflecting assembly (150) in reflecting relation with the beamsplitter (130). An alternate embodiment of the invention substitutes the monolithic structure having the above six components, with a monolithically constructed hollow corner-cube retroreflector (400), wherein one of the retroreflector panels is a reflecting surface (420), another panel (situated at a 45 degree angle to the reflecting surface of the first panel) is a beamsplitter (410), and a third panel is a support panel (430) used to complete the construction of the hollow corner-cube retroreflector (400).</p> |
