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

In recent years, the adoption of near-infrared sensing technology has rapidly expanded across a wide range of fields, including autonomous driving, industrial robots, smartphones, and medical devices. Applications such as spatial recognition using onboard LiDAR and TOF sensors, wearable devices for facial recognition and biometric measurement, and non-invasive medical applications using light are all reaching practical implementation and widespread use, leading to an increasing demand for optical components that support these technologies year by year. Among these, the "bandpass filter," which selectively transmits only specific wavelengths, is becoming increasingly important in development environments as a key component that affects the accuracy and reliability of sensors. At Adachi New Industry Co., Ltd., we offer a standard inventory of near-infrared bandpass filters ranging from 660nm to 940nm to meet these diverse needs. Chapter 1: Why are red to near-infrared bandpass filters attracting attention now? Chapter 2: Basics of bandpass filters and the characteristics of "near-infrared" Chapter 3: Detailed explanation of use cases by wavelength: Roles and market trends from 660 to 940nm Chapter 4: Introduction of standard inventory: A ready-to-use lineup of six wavelengths Chapter 5: Custom design support: Optimal filters tailored for customers Conclusion: The future opened up by near-infrared bandpass filters

The competition for the practical application of quantum computers is accelerating on a global scale. However, one of the barriers faced by researchers and engineers working on development at the forefront is the reality that "components cannot be procured." High-precision optical elements and optical thin films are essential to the foundation of quantum systems, yet suppliers capable of meeting the specific requirements of quantum optics are limited worldwide. Of course, at this point, Adachi New Industries cannot produce all products through film deposition and manufacturing, but we present this co-creation proposal to developers to overcome that barrier together. 01: Quantum Computers and Optical Thin Films 02: Optical Thin Film Products Required for Quantum Systems—Specific Product Groups and Required Specifications 03: Reasons Why Quantum Optical Coatings Are Difficult—Structure of Technical Challenges 04: Co-creation with Master Coatings—Development Process Starting from Small-Scale Prototyping Summary Adachi New Industries' "Master Coatings" will accompany you as a partner to overcome these barriers together, from the initial concept stage of development to the mass production phase. Starting with small-scale prototyping, we will cycle through prototyping and evaluation together, "co-creating" the optical thin films required for quantum devices—this is our co-creation proposal.

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.
