Description

Technical Field

[0001] The utility model relates to the technical field of ultra-stable cavity reflector detection, in particular to a device for detecting the parallelism of an ultra-stable cavity reflector product. Background Art

[0002] Ultrastable cavity refers to Fabry-Perot cavity, which is an optical cavity. It is an optical device based on interference effect and can be used in spectral analysis, laser and fiber-optic communication. FP microcavity is a cavity composed of two parallel mirrors, one or both of which are translucent. They are often used as output ports in lasers, and can also be used to measure the refractive index and thickness of materials. However, if the two mirrors inside the ultrastable cavity are not parallel during use, the ultrastable cavity will not work properly. Therefore, parallelism detection is required. During the detection, a light source can be used for observation. If they are strictly parallel, the interference fringes are concentric rings, and if they are not parallel, they are straight fringes or curved fringes. Ultrastable cavities have a variety of shapes such as cylindrical, conical, and irregular shapes.

[0003] The existing detection device cannot quickly install and disassemble ultra-stable cavities with different shapes during testing, which is a troublesome problem when performing repeated tests and adjustments. For example, the device disclosed in the patent announcement number CN216049720U; therefore, a parallelism detection device for ultra-stable cavity reflector products is proposed.
