Anti-reflective film (AR) allows more visible light to pass through. [Free initial design]

Merchandise for fans has evolved primarily through the combination of "design" and "materials." The beauty of illustrations, printing techniques, and the choice of materials such as acrylic, metal, and fabric have significantly enhanced the appeal of these products. However, the impression we get when we see merchandise is not solely influenced by design and materials. The feelings we experience, such as "beautiful," "eye-catching," or "photogenic," are greatly affected by how light reflects, transmits, and disperses. For example, have you ever had the experience of seeing the room's lighting reflected when displaying an acrylic stand? Or when taking a photo with your smartphone, noticing a flare (a whitish blur) on your favorite character's face, or seeing colors that look different from their true hues? This is not necessarily due to poor design or printing, but rather because the behavior of light has not been adequately controlled. ◆ Merchandise for fans is moving to the next phase of evolution ◆ Merchandise for fans can be transformed significantly with "light" ◆ Proposal: Merchandise for fans that "selects only the favorite" using bandpass filters ◆ Co-creation proposal: Shall we shape the next standard with Adachi New Industry?

The UV-IR cut filter is an optical thin-film filter that selectively removes unwanted light in the ultraviolet (UV) and infrared (IR) wavelength ranges, allowing only specific wavelength bands of light to be transmitted or reflected with high precision. This filter achieves wavelength selectivity by utilizing interference effects through the precise layering of multilayer dielectric films and metal films. Generally, it requires control of film thickness on the order of nanometers, exceeding several tens to over a hundred layers, and its optical properties are determined by multiple parameters such as film thickness accuracy, refractive index of the film material, smoothness of the film interfaces, and adhesion of the films. 1) What is a UV-IR cut filter? 2) Historical background of UV-IR filter manufacturing in Japan 3) Why has overseas manufacturing of UV-IR cut filters progressed? 4) If UV-IR cut filters were to be produced again in Japan... necessary points (hypothesis) 5) Technically important points when selecting UV-IR cut filters 6) Future prospects Conclusion - The efforts of Adachi New Industry Co., Ltd. to focus on domestic production in Japan For more details, please visit our company website.

The Kansai Expo is being held as an international event where cutting-edge technologies, services, and cultural expressions from around the world gather under the grand theme of "Designing a Future Society Where Life Shines" (as of the article dated September 29, 2025). From AI-driven autonomous robots and next-generation mobility to immersive video experiences, space exploration technologies, and future medical and healthcare innovations, a wide range of innovative technologies are being showcased right before the eyes of visitors, providing a valuable opportunity to experience the vision of society's future up close. In our series, we have focused on optical thin films and fine pattern processing (metallization) technologies, which function as the unsung heroes behind these cutting-edge technologies, introducing them over seven installments. Optical thin films enable precise light control, such as reflection, transmission, and wavelength selection, playing an essential role in various advanced devices like sensors, cameras, projectors, and space equipment. Meanwhile, fine pattern processing serves as a foundational technology that supports the high precision of electronic devices, biosensors, and next-generation displays by controlling structures at the nanometer level.

The 2025 Osaka-Kansai Expo will feature the theme "Designing a Future Society Where Life Shines," showcasing numerous cutting-edge visual productions and experiential exhibits. Central to creating immersive video experiences that strongly engage visitors is projector technology. Supporting this performance at its core are optical thin films (optical filters) applied to lenses and optical components. As brightness and resolution increase, the quality of optical thin films directly impacts the clarity, color reproduction, and durability of the images. The "amazingness" of the video technology at this Kansai Expo has evolved beyond merely providing visual information to becoming a means of reconstructing the space itself. In particular, in the field known as "immersive video," stimulating multiple senses such as sight, hearing, and touch allows viewers to be drawn into the narrative, blurring the boundaries between reality and the virtual experience. 【1】The Power of Video Supporting Immersive Experiences 【2】What is a Three-Sided Screen? - The Key to Video Production Supported by Projectors 【3】What are the Representative Pavilions Where You Can Actually See a Three-Sided Screen at the Expo? 【4】What Optical Thin Films are Necessary for Projectors to Achieve a Three-Sided Screen? 【5】What is the Future Where Three-Sided Screens and Projectors are Introduced into Homes?
