    摘要: A thin-film color-selective beam splitter and the method of fabricating the same are disclosed. The method includes the steps of: (i) forming a main prism by a pre-selected material, and deciding a first base angle and a second base angle according to the substance and coating characteristics of the pre-selected material; (ii) coating a first multilayer film and a second multilayer film on two slopes of the main prism, in which tilt angles for coating the first multilayer film and the second multilayer film and tilt angles of light entering and emerging the main prism are different, so that spectra of the first multilayer film and the second multilayer film are different, and the first multilayer film can be a red reflective film and the second multilayer film can be a blue reflective film; and (iii) using the pre-selected material to form interface prisms, and adhering the interface prisms to the main prism, so that light can perpendicularly enter and emerge from surfaces of the prism. Moreover, the method may include a further step of: coating a filtering film on an emerging interface of the main prism for green light. A thin-film color-selective beam splitter can be formed by the above method with a single coating process and can serve as a tri-color beam splitter.

The thickness and ingredient of each of the plurality of dielectric layers having a high refractive index and the plurality of dielectric layers having a low refractive index are determined according to interference theory for all-dielectric thin-film multilayers to make the thin-film multilayer system able to polarize light and to display images in true color. Further, the ingredients of the thin-film multilayer system are dielectric materials that can endure wear and tear, chemicals, and environmental injuries. The thin-film multilayer system can be directly formed on the windshield of a vehicle, otherwise it can be formed on a substrate made of glass or plastic, and then adhered to the windshield.

    摘要: A thermal transfer color-variable ribbon is disclosed, the color appearance of which depends on the variation of viewing angle, which includes a substrate, a releasing agent formed on the substrate, a functional coating, which can be a multilayer thin-film stack of reflection mode or transmission mode, formed on the releasing agent, and an adhering layer formed on the functional coating. The functional coating is designed based on the general theory that describes the thin-film interference phenomena. The functional coating can be formed by alternately stacking dielectrics having high and low refractive indices or dielectric and metal layers. The construction parameters of the all-dielectric stack and the metal/dielectric stack can be chosen in similar way to how parameters are chosen when manufacturing selective band-pass filters, which are designed based on the thin-film interference theory. The color appearance of the printed document, either in reflection mode or in transmission mode, can be selected and optimized as for the filter design. The effect of varying incident angle on color appearance of the functional coating in either mode can also be optimized during the design. Furthermore, the functional coating can be a inhomogeneous thin-film. The refractive index of the inhomogeneous thin film is varied along the growth direction.
