660nm bandpass filter (visible light range): FA sensor, laser, etc.

In recent years, the boundary between beauty and technology has begun to rapidly dissolve. The demand for at-home skincare devices continues to expand globally, with some areas, such as light-based treatment devices (phototherapy), recording growth of over 20% year-on-year as of 2024. These products offer more than just simple "apply and layer" beauty. They provide an experience that precisely delivers physical energies such as light, heat, electric currents, and sound waves to the skin. Let’s pose a question. "What exactly is controlling that light?" One answer lies in optical thin-film technology. Invisible nanometer-scale films quietly but decisively influence the performance of beauty devices. This article will explore the role and potential of optical thin films in the beauty tech field from the perspective of product development and engineering. 1: What is optical thin film? 2: Scenes of optical thin film utilization in beauty tech 3: Points and precautions during design and adoption 4: Future prospects—The fusion of personalized beauty and optical thin films Summary: "Invisible technology" is changing the beauty experience.

"Extract only the desired light" — this is the role of optical components known as band-pass filters (BPF). We will explain the mechanism and selection of BPFs, which are used in various fields such as medical, industrial, and environmental measurement, in an easy-to-understand manner, even without specialized knowledge. Camera sensors, medical fluorescence microscopes, factory appearance inspection devices, environmental measurement sensors — these seemingly completely different devices share a common technical challenge: "accurately extracting only the necessary wavelengths from light that contains countless wavelengths." For example, in fluorescence imaging, it is essential to detect only the weak fluorescence signals amidst strong excitation light. In factory appearance inspection, it is necessary to shut out stray light from daylight and fluorescent lamps to detect only the illumination wavelengths. The optical component responsible for this "light selection" is the band-pass filter (BPF). The name may sound complicated, but once you understand its mechanism, it is based on a very simple principle. We will present the basic concepts of BPFs, manufacturing principles, and points for application selection in a format that can be read in five minutes.

The way of presenting in the entertainment sector is changing significantly due to the expansion of expos, immersive exhibitions, and experiential museums. Traditionally, the focus was on enhancing visual and lighting effects, but now the competition lies in "experience design," which revolves around "how visitors feel and how they remember" their experiences. With the proliferation of social media, there is a demand not only for "instant impact" but also for "shareable experiences" and "experiences that make people want to return." In this context, the key to differentiation is the "quality of light." An important role in this is played by optical thin-film technology, which precisely controls the wavelength of light. Optical thin films enable visual experiences that cannot be achieved with conventional lighting or displays by designing transmission, reflection, and absorption at the nanoscale. In the future of entertainment, light is evolving from a mere means of presentation to a design element that constitutes the experience itself. 【1】Exhibitions that change depending on the viewer 【2】Productions with two worlds 【3】Designing the space itself 【4】Next-generation exhibitions that integrate with sensors 【5】Potential applications in the entertainment sector Summary: The option of co-creation For more details, please refer to our company website.

The evolution of food tech goes beyond mere efficiency and automation. Alternative proteins, cultured meat, smart agriculture, food waste reduction, personalized nutrition design—what supports the forefront of these advancements is sensing technology that visualizes "invisible information." At the core of this is "light." Optical thin films are key components that read the state of food and raw materials non-contact, quickly, and with high precision by selectively transmitting, reflecting, or blocking specific wavelengths. We, Adachi New Industry Co., Ltd., propose co-creation with the food tech sector as a partner that selects, controls, and designs light, including environmental resistance. 1. Entering an era of "seeing" food quality through wavelengths 2. Advancements in "foreign substance inspection" and optical thin films 3. Co-creation with food tech companies! 4. Technical support from the conceptual stage Adachi New Industry Co., Ltd. integrates spectral design, film formation technology, and environmental durability evaluation, accompanying you from the conceptual stage to mass production implementation as a co-creation partner that supports food safety, quality, and experiential value. Shall we create next-generation food tech products together, starting from the design of light? For more details, please check our company website.
