Description

Technical Field

[0001] The utility model relates to the technical field of film coating devices, and more specifically to a film coating device for a broadband depolarizing beam splitter prism. Background Art

[0002] The depolarizing beam splitter prism is made by coating a multilayer interference film on the inclined surface of a right-angle prism and then gluing it into a cubic structure, so that the P polarization component and the S polarization component of the incident light have similar beam splitting characteristics. After being split by the beam splitter prism, the original proportional relationship between the horizontal polarization and the vertical polarization in the incident light is maintained as much as possible. The optical characteristic separation of P light and S light is less than 5%, the dispersion is low, the color neutrality is good, and the wavelength covers 400-1600nm. It is widely used in interferometers and various imaging instruments.

[0003] The Chinese patent document with publication number CN216605689U in the prior art provides a film coating device for a broadband depolarizing beam splitter prism, comprising a box, a film coating assembly is arranged on the top of the box, one end of the film coating assembly is fixedly connected to the left side of the box, and the other end extends to the inside of the box and is fixedly connected to the inner top wall thereof, and the inner bottom wall of the box is provided with a driving mechanism fixedly connected to the inner wall of the box. The film coating device for the broadband depolarizing beam splitter prism is provided with a driving mechanism, and a motor is started to drive the driving wheel to rotate, so that the meshing driven wheel drives the rotating shaft to rotate, and the rotating disk is rotated under the support of the U-shaped block, thereby expanding the spraying range of the top, and at the same time, the electric push rod is started to push the tooth plate to move up and down, so that the meshing gear drives the rotating rod to rotate, thereby driving the second clamping block to rotate, and since the connecting shaft is rotatably connected to the fixed plate, it can also be turned over, thereby completing double-sided coating, and achieving the purpose of wide spraying range and double-sided spraying.

[0004] However, the device still has the following shortcomings: although it can coat the depolarizing beam splitter on both sides, it is difficult to fix depolarizing beam splitters of different sizes, resulting in a small application range of the device. At the same time, the shunt tube is fixed, which easily leads to uneven thickness of the coating layer. In view of this, we propose a coating device for broadband depolarizing beam splitter prisms.
