UV cut filter: A filter that efficiently cuts ultraviolet rays.

In the world of architecture and interior design, the "experiential value of space itself" is beginning to change significantly. Until now, the performance expected from building materials focused primarily on basic functions such as strength, weather resistance, thermal insulation, and workability. However, in recent years, in addition to these, the "sensory value of how one feels in that space" and "the impression it gives" have become increasingly important. 1.

Integration with virtual space production and transparent displays 2-3. Adding functionality to interior materials 3. Sensing and optical design required in the era of smart architecture 4. The importance of "co-creation" in the architecture and interior design fields Summary: Optical thin films are a technology for designing the "future of space." A new era is beginning where new architectural values are emerging by crossing previously separate technological domains. Adachi New Industry Co., Ltd.'s "Takumi Coating" proposes new possibilities for co-creation in the architecture and interior design fields through optical thin films and patterning processing.

The areas where drones are active are rapidly expanding from surveying, infrastructure inspection, agriculture, logistics, and disaster prevention to defense and security fields in recent years. In addition to the demand for high-precision sensing in the private sector, the requirements for optical systems mounted on drones are becoming increasingly stringent in defense applications such as border surveillance, information gathering, search and rescue, and unmanned operational support. While the miniaturization and weight reduction of the aircraft are progressing, the proposition of "obtaining more precise information in harsher environments" remains unchanged. One key to solving this contradiction is optical thin film technology. Optical thin films, which control the reflection, transmission, and blocking of light at the nanometer level, are a technology that fundamentally enhances the performance of mounted sensors across the visible light, near-infrared, and thermal infrared ranges. We will introduce the role that optical thin films play in drone development from the perspectives of industry, agriculture, and defense. 1.

Optical filters are important devices used to extract only the necessary wavelengths from light or to block unnecessary wavelengths. They are utilized in a wide range of fields, from cameras and displays that we commonly see, to spectroscopic analysis devices used in medical and bio fields, as well as in industrial applications such as laser processing and optical communication. Light encompasses a broad wavelength range, including ultraviolet, visible, and infrared light; if the desired light cannot be precisely controlled, it can lead to issues such as false detection, increased noise, and decreased image quality. This is where the concepts of "cut-on" and "cut-off" come into play. These concepts indicate the boundary where light begins to transmit and the boundary where transmission ends, forming the foundation of optical filter design. 1. Definition and Basic Principles of Cut-On and Cut-Off The most important parameters for correctly designing and evaluating optical filters are the "cut-on wavelength" and "cut-off wavelength." These are not just names; they are reference values that numerically define the effective performance of the filter, specifically which wavelength ranges are transmitted and which ranges are blocked. 2.

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.
