MONOLITHIC OPTICAL ASSEMBLY

摘要

In accordance with the invention, an improved optical assembly (200) having a monolithic structure is provided. The monolithic optical assembly (200) is useful in interferometers to achieve a fringe effect in a Fourier transform spectrometer, and comprises top (260) and bottom members (270) which are joined into a monolithic structure by first (210) and second support members (220) and a beamsplitter (130). The assembly also comprising a first reflecting assembly (140) in reflecting relation with the beamsplitter (130) . An alternate embodiment of the invention has an added reflecting assembly (150) in reflecting relation with the first reflecting assembly (140) and th e beamsplitter assembly (130), which allows for the use of multiple wavelength light sources to achieve a fringe effect in a Fourier transform spectrometer .
