Abstract
High-precision monolithic optical assemblies are formed using low-cost standard optical components, such as wedge plates and/or wedge second surface mirrors. By rolling and/or shifting the components relative to each other with matched optical surfaces in contact, a precise alignment solution is found for a particular optical assembly. The resulting arrangement of components can be bonded or held together so as to form a high-precision monolithic optical assembly, which can be inserted into an optical system, according to the assembly's function. The functionality of the monolithic optical assembly can be independent of the optical system in which it is used.
