Abstract: In a Michelson interferometer, two plane mirrors of the mirror unit (50) are embodied as two plane mirrors (51, 52) of different sizes, disposed eccentrically and parallel to one another. A hollow shaft (63), rotatably supported in a bearing block (62) and driven by a drive unit (65), is also provided, which is disposed between a beam splitter and the mirror unit (50) and whose axis of rotation (61) coincides with the axis of rotation of the mirror unit (50). The mirror unit (50) is secured to the hollow shaft (63) in such a way that the axis of rotation (61) of the hollow shaft passes through the mirror face of the smaller plane mirror (51), whose axis of rotation forms an acute angle (.beta.) with the vertical to the smaller plane mirror (51), so that the two beams formed at the beam splitter (1) pass, via the tilted mirrors, through the hollow shaft (63) to strike the centrally disposed mirror face of the smaller plane mirror ( 51), are reflected by it to the opposite mirror face of the larger plane mirror (52) and from there to two stationary plane mirrors (71, 72) in such a way that they strike the stationary plane mirrors (71, 72) vertically, and--reflected by those mirrors--take the same path in the opposite direction, recombine at the beam splitter, and are focused by means of an optical element onto a detector (4).

Abstract: An interferometer including a beamsplitter and fixed and movable cube corner reflectors is adapted for use in a Fourier-transform infrared (FTIR) spectrometer. The spectrometer includes a cast metal base, such as of aluminum, with the interferometer including an IR source housing formed integrally with the base for dissipating heat via conduction. The IR source housing is hollow and open at the top for receiving a removable opaque printed circuit board (PCB) which is coupled to and provides support for and electrical current to an IR source within the housing. The housing includes two apertures in lateral portions thereof. An IR beam is directed by the source through a first aperture to the Michelson interferometer, while a second aperture is adapted to receive a fiber optic light guide to allow for direct viewing of the IR source in a safe manner without removing the PCB cover of the housing. An interferometer chamber is isolated from a sample chamber, both of which chambers may be independently purged and are further isolated from the spectrometer's electronic circuitry. The spectrometer includes a minimum number of reflectors outside of the interferometer for reduced light loss and improved signal-to-noise ratio with the interferometer providing an output IR beam to a first focus mirror which horizontally focuses the beam on and directs the beam through the sample and thence onto a second focus mirror which vertically focuses the beam on a closely spaced IR detector integrated in a printed circuit board.

Abstract: A Fourier Transform Raman Spectrometer system includes a folded V laser cavity. A first leg of the folded V laser cavity is defined by a highly reflective end mirror and a dichroic fold mirror and a second leg of the folded V laser cavity is defined by the fold mirror and an output coupler. A solid-state laser gain medium is disposed in the first leg of the folded V laser cavity and is pumped by a pump source aligned with the optical path of the first leg of the laser cavity and radiating through the fold mirror. The fold mirror is highly transmissive at the wavelength of pump radiation from the pump source and highly reflective at the laser output wavelength. An output beam from the laser is passed through a tuneable filter comprising an acousto-optic device and is directed at a sample to be analyzed. Light reflected from the sample is directed to a Raman Spectrometer for analysis.

Abstract: An optical or Fourier infrared Fourier spectrometer with a two-beam interferometer with which the mirror drive is effected via two retroreflectors which are located on two 180.degree. displaced arms of a double pendulum. Deflecting mirrors are arranged between the beam splitter and the retroreflectors. The otherwise usual retroreflecting mirrors are not present.

Abstract: A device according to the present invention includes an interferometer which produces interference fringes from light received from a light source. The interference fringes are imaged onto a photo-diode array which transforms the imaged interference fringes into a single set of electric signals. The single set of electric signals is digitized and stored as a group of consecutive data points which represent an interferogram signal containing a DC component. The data points are processed to obtain moving average values representing the DC component of the interferogram signal. The moving average values are subtracted from the data points to obtain a clean interferogram signal which is Fourier-transformed to obtain a spectrogram of the light source.

Abstract: Two corner cubes are opposed to share one or two mirror surfaces in common thereby integrally forming two mirror groups, and driven to be reciprocatively rotated in a plane including two opposite edges thereof or a symmetry plane including an edge defined by the two common mirror surfaces, while a beam splitter is provided in front of the two corner cubes for reflecting a part of incident light and guiding the same to one of the corner cubes as well as transmitting the remaining part of the incident light and guiding the same to the other one of the corner cubes while causing interference between light components reflected from the corner cubes. According to the present invention, a moving mechanism may simply cause reciprocative rotation movement about one center of rotation, and adjustment in assembling is extremely simple and easy to allow reduction in manufacturing cost. A double corner cube member, which can be formed of the same material, is stable against disturbance such as vibration and temperature change. When plane mirrors for forming the corner cubes are manufactured by machining such as cutting or grinding, it is possible to perform assembling and working in high accuracy.
