Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wave plates, in particular to a glued wave plate. Background Art
[0002] A wave plate is an optical device that can produce an additional optical path difference between two mutually perpendicular light vibrations. It is usually made of birefringent wafers such as quartz, calcite or mica with precise thickness. Its optical axis is parallel to the surface of the wafer. A bonded wave plate is a wave plate bonded together with glue.
[0003] Chinese patent announcement number CN212965498U proposes "a glued wave plate". The technical solution proposes the problem that "the first wave plate in the prior art is too thin, with a thickness of 0.04mm*0.09mm, and is easy to break and difficult to process. Before the crack, it can generally only have an area of about 10mm*10mm, and then it is coated on both sides and cut into small particles of about 1mm*2mm. The operation is inconvenient during the processing and the subsequent mounting process of the user". The utility model provides the following technical solution: "It is fixed to the substrate through the adhesive layer, so that the glued wave plate has a greater thickness than the simple wave plate, and due to the support of the substrate, the glued wave plate is not easy to break, which reduces the difficulty of processing, and before the crack forms small particles, the area of the glued wave plate can be increased. Therefore, after the crack, more small particles can be formed at one time, which increases production capacity and reduces prices. At the same time, it is easy to mount and use later. This wave plate with an adhesive layer does not affect the performance."
[0004] The above scheme also has the following defects: the above wave plate lacks an adjustment structure, and the experimenter needs to adjust it manually during the experiment, which brings inconvenience to the experimenter. Therefore, a glued wave plate is proposed to solve the above problem. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a glued wave plate, which has the advantage of being easy to use.

[0008] Furthermore, the crystal wave plate is located at one end close to the left side of the supporting base plate, and the crystal wave plate is vertically installed on the top of the supporting base plate.
[0009] Furthermore, the thickness of the tempered glass sheet is smaller than the thickness of the crystal wave plate, and the thickness of the sapphire sheet is smaller than the thickness of the tempered glass sheet.
[0010] Furthermore, the lengths of the two protective shells are both shorter than the length of the supporting base plate, the exteriors of the two protective shells are both rectangular structures, and the tops of the two protective shells are both open structures.
[0011] Furthermore, the two movable bottom blocks slide left and right inside the two protective shells respectively, and the heights of the two movable bottom blocks are both smaller than the height of the protective shells.
[0012] Furthermore, the heights of the two limit vertical plates are both greater than twice the height of the crystal wave plate, the heights of the two metal slides are half the height of the limit vertical plates, and the two metal slides respectively penetrate the inner sides of the two limit vertical plates.
[0013] Furthermore, the quarter wave plate is located on the top of the supporting base plate, and the two magnets are located on the top of two metal sliding strips respectively.
[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0015] The bonded wave plate reduces the refraction of light through the sapphire plate and can also protect the crystal wave plate. After that, the light passes through the crystal wave plate and the tempered glass plate from the sapphire plate to be emitted to the quarter wave plate. The two linear modules respectively drive the two movable bottom blocks to move left and right, which can drive the quarter wave plate between the two metal slides to move closer to and away from the crystal wave plate. The quarter wave plate is pulled upward so that the two metal slides are respectively adsorbed by the two magnets to restrict the quarter wave plate. At this time, the light passes through the crystal wave plate alone for testing, thereby achieving the effect of easy use. BRIEF DESCRIPTION OF THE DRAWINGS

The exteriors of the two linear modules 6 are protected by the two protective shells 5 respectively. Moving bottom blocks 7 are fixedly installed on the top output ends of the two linear modules 6. The two moving bottom blocks 7 slide left and right inside the two protective shells 5 respectively. The heights of the two moving bottom blocks 7 are smaller than the height of the protective shells 5. The two moving bottom blocks 7 are driven to move left and right inside the two protective shells 5 respectively by the two linear modules 6.
[0024] The tops of the two movable bottom blocks 7 are fixedly installed with limit vertical plates 8, and the two limit vertical plates 8 are driven to move synchronously by the two movable bottom blocks 7. The heights of the two limit vertical plates 8 are greater than twice the height of the crystal wave plate 1. Metal slide bars 9 are slidably installed inside the two limit vertical plates 8.
