Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0027] like figure 2 , image 3 Shown, the first embodiment of the present invention. The optical etalon includes a first support 41 , a second support 42 , a first mirror 31 , and a second mirror 32 . The first support member 41 is provided with a guide hole, and the diameter of the guide hole is related to the size of the second support member 42 . like Figure 4 Shown is a side cross-sectional view of the first support 41, defining a first end 413 of the first support 41 and a second end 414 opposite to the first end 413 along the axial direction of the guide holes 411, 412, the first support ...

Abstract

The invention provides an optical etalon which comprises a first supporting piece and a second supporting piece. The first end of the first supporting piece is provided with a first reflecting mirror. The first end of the second supporting piece is provided with a second reflecting mirror. The first supporting piece is also provided with a guide hole. At least a part of the second supporting piece is contained in the guide hole and can move in the axial direction of the guide hole. When the second supporting piece is located in the guide hole, the first reflecting mirror and the second reflecting mirror are parallel to each other. The optical etalon has the advantages that the distance between the first reflecting mirror and the second reflecting mirror is easy and convenient to adjust, the parallelism between the two reflecting mirrors can also be guaranteed, and therefore the rate of finished products is high.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to an optical etalon. Background technique [0002] With the continuous advancement of modern communication and measurement technology, the requirements for wavelength output and optical channel locking technology are getting higher and higher, which also puts forward higher requirements for the performance and stability of optical etalons to a certain extent. Optical etalons include solid optical etalons and hollow optical etalons. Solid optical etalons can only achieve simple fringe interference, but cannot obtain high-precision optical interference lines and etalon effects. At this point, air-gap optical etalons characteristics are even better. However, it has always been a difficult problem to ensure the parallelism of the two mirrors during the manufacture of the air-gap optical etalon, which also limits the application of the air-gap optical etalon to a certain extent. [000...
