ND filter is a filter used to adjust the transmission rate!

At the 2025 Osaka-Kansai Expo, cutting-edge technology and cultural expression were beautifully integrated, with projector technology fully utilized to stimulate the senses of visitors. Immersive video presentations and interactive exhibition experiences, both inside and outside the pavilions, were made possible through projection with high brightness, high resolution, and wide color gamut. It may be a bit late to say this, but from the perspective of "Could projectors hold the key to future visual expression?", I have summarized the optical components used in projectors in a way that can be understood in five minutes. Please feel free to read on. 【1】Changes in the projector market 【2】Comparison of LCD, DLP, and LCOS 【3】General optical structure of projectors 【4】Types and specifications of optical filters for projectors 【5】Future trends in projectors and the position of Japanese thin-film manufacturers Conclusion - Nevertheless, Adachi New Industry is committed to domestic production For more details, please visit our company website.

The 2025 Osaka-Kansai Expo is a grand stage where cutting-edge technologies and cultures from around the world intersect. In particular, the pavilions of Middle Eastern countries such as Saudi Arabia, the UAE, Qatar, and Oman resemble a miniature future city, showcasing advanced architecture, smart energy, and AI-controlled urban infrastructure, allowing visitors to experience "future urban living." These Middle Eastern countries are actively promoting sustainable urban development and smart city initiatives, with significant expectations for industrial revitalization. Optical filters and thin-film technology can be applied across a wide range of fields, including renewable energy facilities, transportation infrastructure, healthcare, and security. Adachi New Industries aims to support the technological foundation of these future cities and contribute to industrial innovation on a global scale. 【1】 Experiencing the Future City at the Kansai Expo 【2】 The Role of Optical Thin Films in the Revitalization of Middle Eastern Industries 【3】 The Vision of Future Cities Shaped by Optical Technology 【4】 A Bridge of Friendship Through Optical Filters.

The signature pavilion of the 2025 Osaka-Kansai Expo, "The Future of Life," is a place that directly confronts the fundamental questions humanity has long grappled with: "What is life?" and "Where does humanity reside?" Here, androids (humanoid robots) created using the latest artificial intelligence and intricate modeling technology will appear before visitors as beings that transcend mere machines. Visitors may find themselves pausing to ponder, "Is this human, or is it a machine?" as they engage with the android's gaze, gestures, and expressions. The encounter with androids that not only resemble humans but also possess conversational and emotional capabilities will provide an experience that is unlike anything encountered in daily life. In that moment, we will feel the boundary that separates humans and machines becoming blurred. [1] What if we use optical filters as the "sensory organs" of the androids?

On November 1, 2024, I participated in the Optical Thin Film Research Meeting held at the Tokyo: Mechanical Engineering Promotion Hall. This time, we moved from the usual basement level 2 to the 6th floor, and the venue was a large space with two screens, making it very easy to see and hear. The Optical Thin Film Research Meeting was established in 2011. It has two main objectives: 1) To revitalize the field of optical thin films in Japan. 2) To advance standardization efforts related to optical thin films and protect Japan's national interests. Our company has been participating since the initial launch in 2011. This is the 52nd meeting of this historic research group.
