Information on standard stock items (optical filters)

Sports are constantly evolving. The lightweighting of equipment, the high-strength of materials, form optimization through data analysis, and the high functionality of apparel—technological innovations for improving competitive performance are now spreading not only among top athletes but also across all sporting environments. In recent years, advancements in sensor technology and AI analysis have significantly shifted sports from "sensation" to "science." However, what underpins this transformation is, in fact, "light." Visibility, tracking, sensing, and presentation—all these aspects utilize light information, and it is optical thin film technology that influences their accuracy and comfort. Now, this "technology that controls light" is poised to unlock new possibilities in sports. It is not just a simple coating; it is an advanced spectral design technology that selects wavelengths, controls reflection, and blocks unwanted light. This technology enhances athletes' decision-making abilities, improves sensor accuracy, and serves as a foundational technology for optimizing the competitive environment itself. ◆ Enhancing athlete performance × Optical thin films ◆ Data sports × Optical filters ◆ Integration with biosensing ◆ Towards future sports devices For more details, please check our company website.

In the development of coating materials for semiconductors and functional chemicals, the evaluation of resistance to electromigration and ion migration has become an unavoidable and important theme. On the other hand, migration is not a phenomenon that can be simply determined by material properties alone. The differences in insulating films, protective films, and coating materials interact with wiring materials and current conditions in ways such as hygroscopicity, ion residue, barrier properties, dielectric characteristics, film thickness, film density, and interfacial adhesion, ultimately manifesting as wiring degradation or insulation breakdown. However, in actual evaluation settings: ◆ The wiring structure and material conditions differ with each evaluation. ◆ The effects of materials and structural factors cannot be separated. ◆ Reproducibility and comparability of evaluation results are difficult to achieve.

There are surprisingly many situations around us where half mirrors, which look like mirrors but actually allow light to pass through, are used. For example, they are essential optical components in smartphone facial recognition and car head-up displays. Half mirrors play a role in skillfully reflecting and transmitting light, delivering images and information more conveniently and precisely. This time, we have summarized the mechanism of half mirrors, their uses, and the future evolution of technology in an easy-to-understand manner that can be grasped in five minutes. 【1】What is a half mirror? 【2】Difference between half mirrors and magic mirrors 【3】Structure of half mirrors 【4】Applications of half mirrors 【5】Points to consider when selecting half mirrors 【6】Future prospects of half mirrors For more details, please visit our company website.

At Adachi New Industry Co., Ltd., we prepare standard stock items that are easy to verify in order to facilitate smoother product development for our customers. Gold mirrors (Au mirrors) are optical elements that use the precious metal "gold (Au)" as a reflective film material, exhibiting an extremely high reflectivity (>96%) in the infrared spectral range (800 nm to 2 µm). Please make use of them. ◆◆ Are you facing any of these issues? - The performance varies significantly depending on the reflective wavelength range of the gold mirror, requiring technical judgment to select the most suitable specifications for the application. - There are differences in quality parameters such as film thickness accuracy, uniformity, adhesion strength, and surface roughness, making selection difficult. - Optical components using high-purity gold have complex manufacturing processes and are easily affected by material procurement. - Price differences can be significant due to fluctuations in gold costs and the precision of manufacturing equipment, making simple price comparisons challenging. - The wavelength range and incident angle characteristics may not match requirements, leading to risks and costs associated with reordering. - It is difficult to find processing sources that can produce stable prototypes in small quantities.
