A method for surface shape control of optical elements based on target-substrate eccentric deposition includes the following steps: First, select the coating material for the surface shape control layer, calculate the non-uniformity of the film thickness distribution of the coating material under different target-substrate eccentric angles, and determine the actual target-substrate eccentric angle for preparing the surface shape control layer; next, fit the calculated film thickness distribution of the surface shape control layer under the target-substrate eccentric angle to obtain the compensated surface shape power value achieved by the surface shape control layer within a certain deposition time; then, determine the actual deposition time for preparing the surface shape control layer based on the power value to be compensated for the optical element; finally, prepare the surface shape control layer using magnetron sputtering technology. This invention achieves surface shape control by adjusting the relative eccentricity angle between the target and the substrate during magnetron sputtering deposition, adapting to any surface shape optical element without modifying hardware and without affecting the element's optical performance; the thickness of the surface shape control layer is significantly reduced compared to traditional methods, which helps to improve the damage threshold of laser thin film elements.

This application relates to the fields of photovoltaic and semiconductor technology, and more particularly to a coating apparatus and equipment to solve the problems of low coating efficiency and high coating cost in coating devices. The coating apparatus includes a process chamber, a conveying component, multiple sets of reactive gas jetting components, and a detection component. The process chamber is configured to provide coating space, the conveying component is configured to continuously convey the product during the coating process, and the multiple sets of reactive gas jetting components are arranged in the process chamber sequentially along the conveying direction of the conveying component. The detection component is located in the process chamber and is configured to detect the position of the product conveyed by the conveying component. Some reactive gas jetting components are activated based on the product being in the corresponding position, while the remaining reactive gas jetting components are deactivated. This coating apparatus replaces the method of coating products using time-controlled reactive gas jetting components, thereby improving coating efficiency and reducing coating costs.
