Monolithic optical assembly
First Claim
1. A monolithic optical assembly for use with an interferometer, comprising:
- a top member;
a bottom member;
a first support member bonded to a first portion of said top member and to a first portion of said bottom member;
a second support member bonded to a second portion of said top member and to a second portion of said bottom member;
a first mirror assembly having at least one reflecting surface, wherein said first mirror assembly is bonded either to said first support member and said top member or said bottom member, or to said second support member and said top member or said bottom member; and
a beamsplitter assembly having a surface having a beamsplitter coating, said surface being in reflecting relation with said first mirror assembly, wherein said beamsplitter assembly is bonded to a third portion of said top member and to a third portion of said bottom member;
wherein said bonding of said first and second support members and said beamsplitter assembly to said top and bottom members creates a substantially stable, substantially vibration and shock resistant structure regarding said reflective relationship between said first mirror assembly and said beamsplitter assembly.

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.
