[0002] At present, optical coating of optical components is to deposit one or more layers of optical materials on the surface of the optical components to change their optical properties and performance. In the actual optical coating process, there is a diversity of optical component sizes. Different optical components have different sizes and forms, including differences in diameter, thickness, shape, etc., which makes it difficult for one fixture to be suitable for optical components of multiple different sizes; the complexity of the shape of optical components. The shapes of some optical components are very complex, such as aspheric mirrors, prisms, etc. These optical components with complex shapes are difficult to fix and position with traditional fixtures; due to the variety of sizes and form structures of optical components, the applicability of fixtures to various optical components is limited, that is, the applicability and compatibility of optical component fixtures are not high. Traditional fixtures are usually designed to have fixed shapes and fixed sizes. An optical component with fixed shape and fixed size corresponds to a traditional fixture with fixed shape and fixed size. Traditional fixtures are almost equivalent to disposable consumables, resulting in a large number of traditional fixtures being wasted and increasing costs. Summary of the invention

The square through holes 107 are fixed The non-supporting surface of the base 101 is provided with a positioning rail, a handle, and a positioning support 104. The first positioning rail 102-1 and the second positioning rail 102-2 are respectively fixed on a pair of parallel sides of the square through hole 107. The first handle 103-1 and the second handle 103-2 are symmetrically fixed on the edge area of ​​the non-supporting surface of the base 101. Both ends of the first positioning support 104-1 and the second positioning support 104-2 are placed on the limiting rails of the first positioning rail 102-1 and the second positioning rail 102-2.It should be noted that when the base 101 is laid flat, the surface seen from above is a non-support surface, and the surface seen from the bottom of the base 101 is a support surface. The purpose of setting the square through hole 107 on the base 101 is to place the positioning support body 104. For example, the square through hole 107 is set to a 50CM×50CM square or a 90CM×90CM square (viewed from above). The positioning rail controls the sliding track of the positioning support body 104. In the optical coating process, one or more layers of metal (or dielectric) thin films need to be coated on the surface of the optical element. Since the use scenarios of each optical element are different, the size and shape of the optical element vary. Of course, the positioning The adjustable fixture for positioning supports is for optical elements with at least one plane surface. One surface of the optical element is placed on the first positioning support 104-1 and the second positioning support 104-2. The spacing between the first positioning support 104-1 and the second positioning support 104-2 is adjustable. For example, taking the square through hole 107 as a square of 50CM×50CM as an example, the surface of the optical element supported by the first positioning support 104-1 and the second positioning support 104-2 is a rectangle. The width of the first positioning support 104-1 and the second positioning support 104-2 (the upper surface on which the optical element is placed, and the horizontal upper surface) is 5 CM as an example, the adjustment spacing between the first positioning support 104-1 and the second positioning support 104-2 is 0CM to 40CM. According to the size and form structure of the optical element, the spacing between the first positioning support 104-1 and the second positioning support 104-2 is adjusted. For example, the optical element is a cube with a specification of 30CM×30CM×30CM, and the spacing between the first positioning support 104-1 and the second positioning support 104-2 is adjusted to 20CM. CM or 15CM, both are acceptable, with the standard being that the fixture can be stably placed on the first positioning support 104-1 and the second positioning support 104-2; the surfaces of the first positioning support 104-1 and the second positioning support 104-2 supporting the optical element are horizontal, and the optical element has at least one plane, and the plane of the optical element is placed on the surfaces of the first positioning support 104-1 and the second positioning support 104-2 supporting the optical element, and the weight of the optical element forms a clamping effect; the first handle 103-1 and the second handle 103-2 are symmetrically arranged, firstly, it is convenient to send the fixture and the optical element into the coating chamber or take it out of the coating chamber, and the symmetrical arrangement makes it easy for the processing personnel to control the force, and the optical element can be kept in a stable state during the transfer of the optical element;Second, the first handle 103-1 and the second handle 103-2 also serve as guardrails. Even if an accident occurs to the optical element, for example, the positioning support adjustable fixture tilts due to the error of the processing personnel, the first handle 103-1 and the second handle 103-2 can also serve as guardrails, so that the optical element is not likely to fall to the ground and be damaged; the first positioning slide rail 102-1 and the second positioning slide rail 102-2 are higher than the first positioning support body 104-1 and the second positioning support body 104-2, and the first positioning support body 104-1 and the second positioning support body 104-2 are The two ends of the first positioning support 104-2 are high and the middle section is low. First, the center of gravity is lowered, so that the center of gravity of the positioning support adjustable fixture and the optical element is lowered, the stability of the positioning support adjustable fixture and the optical element is increased, and the optical element can be better protected. Second, the two ends of the first positioning support 104-1 and the second positioning support 104-2 cooperate with the first positioning slide rail 102-1 and the second positioning slide rail 102-2 to play the role of a guardrail, so that the optical element is not easy to fall to the ground and be damaged; symmetrical screw holes are set on the first positioning support 104-1; Figure 1 The visible screw hole on the first positioning support 104-1 is the first screw hole 106-1, and symmetrical screw holes are provided on the second positioning support 104-2. Figure 1 The visible screw hole on the second positioning support body 104-2 is the second screw hole 106-2; when the positions of the first positioning support body 104-1 and the second positioning support body 104-2 on the first positioning slide rail 102-1 and the second positioning slide rail 102-2 are determined, a screw is screwed into the screw hole to fix the positions of the first positioning support body 104-1 and the second positioning support body 104-2.
