The invention discloses a vacuum coating machine for preparing a large-caliber optical thin film element, and belongs to the field of thin film optics. Compared with a conventional vacuum coating machine, The vacuum coating machine comprises a vacuum module, an evaporation source module, a film thickness / speed monitoring module and a temperature control module, and further comprises a planetary rotary clamp module with a special design; and the vacuum coating machine is characterized in that the revolution radius of a planetary rotary clamp is adjustable, and a large-caliber optical thin filmelement with the size larger than the radius of a vacuum coating chamber can be manufactured. In addition, a correction baffle module is arranged between the evaporation source module and the large-caliber optical film element, and the thickness distribution of a thin film on the large-caliber optical thin film element in the vacuum coating process is optimized. The vacuum coating machine is particularly suitable for preparing large-caliber optical thin film element with the size larger than the radius of the vacuum coating chamber, and the preparation of the large-caliber optical thin film element cannot be realized by the conventional vacuum coating machine.
Description
technical field [0001] The invention relates to the technical field of vacuum coating machines, in particular to a vacuum coating machine for preparing large-diameter optical thin film elements. Background technique [0002] With the development of science and technology, the design of optical system is becoming more and more sophisticated, and the aperture of optical components is also getting larger. Usually, a specially designed optical film must be coated on the surface of the large aperture optical element to improve the performance of the optical element to meet the performance requirements of the optical system. Vacuum coating technology has the characteristics of simplicity, convenience, easy operation, fast film forming speed, and high film quality. It is the most widely used technology in the preparation of optical thin films. [0003] For the preparation of large-diameter optical thin film components, domestic and foreign vacuum coating machines are mainly equipp...
