Abstract
In accordance with the invention, an improved optical assembly having a monolithic structure is provided. The monolithic optical assembly is useful in interferometers to achieve a fringe effect in a Fourier transform spectrometer, and comprises top and bottom members which are joined into a monolithic structure by first and second support members and a beamsplitter. The assembly also comprising a first reflecting assembly in reflecting relation with the beamsplitter. An alternate embodiment of the invention has an added reflecting assembly in reflecting relation with the first reflecting assembly and the beamsplitter assembly, which allows for the use of multiple wavelength light sources to achieve a fringe effect in a Fourier transform spectrometer.
