Description
Technical field
The utility model relates to a kind of Michelson interferometer collimator apparatus.
Background technology
Michelson interferometer is that American Physical scholar Michelson in 1883 is cooperated with Mo Lei, is the precision optical instrument that research " ether " is drifted about and manufacture and design out.It utilizes divide amplitude to produce twin-beam to realize interfering.Equal thickness interference or equal inclination fringe is produced, for precision measurements such as length, refractive index, wavelength, thickness by adjusting this interferometer.Mainly contain the level crossing that M1 and M2 two is mutually 90 degree in instrument, by adjusting the axis of two minute surfaces, making film viewing screen manifests striped, thus measuring.This instrument is widely used in commercial production, is also one of classical instrument of College Physics Experiments of Optics.
At present, Michelson interferometer calibration system mainly relies on visual inspection, regulates M1 and M2 screw behind, determines light reflection position.The method not only easily makes experimenter's eye fatigue, has again obvious danger when irradiating experiment to operate laser source; Meanwhile, the effect shortcoming that the method regulates, after being especially suitable for a period of time, the interference fringe sharpness of generation, contrast, saturation degree all cannot meet the requirement of precision measurement.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide a kind of structure Michelson interferometer collimator apparatus simple, easy to adjust.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of Michelson interferometer collimator apparatus, comprise bracing frame, support frame as described above top is provided with diaphragm, described diaphragm center is provided with the through hole passed for reflected light, described diaphragm is provided with two-dimensional direct angle coordinate system and scale for initial point along level and vertical direction with the through hole center of circle, bottom support frame as described above, is provided with horizontal base, be provided with for the buckle with interferometer arm releasable connection bottom described horizontal base.
Further, support frame as described above is provided with the elevating lever for regulating its height.
Further, described horizontal base is provided with level meter.
Further, described diaphragm is iris, and the range of adjustment of its through hole is 1mm< R<5mm.
Further, described diaphragm is circular or square.
Compared with prior art, the utility model has following beneficial effect: (1) makes whole light path all be on corresponding axis after the utility model collimation, effect of each components and parts can be given full play to, reduce the loss such as scattered light, diffuse reflection, interference pattern is more clear bright, and measurement result is more accurate.(2) the diaphragm coordinate system in the utility model can not only regulate by auxiliary optical path axis, is more convenient to the observation of equal inclination interference angle, clearly can reflect that M2 is with the angle between M1.(3) the utility model is the organic assembling of traditional diaphragm and coordinate system, level meter, elevating lever, cheap, and structure is simple, is convenient to promote.(4) the utility model is in the process to Michelson interferometer collimation and calibration, and eyes need not look at light path straight, safety and environmental protection, fast simple and direct; Simultaneously by coordinate system, the orientation of each minute surface displaced central axis line can be found fast, and then quick adjustment position; Additionally by the change aperture of the diaphragm, accurately can control the position of each minute surface, thus ensure that the acquisition of distinct interference pattern.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
