Multi-band pass filter (dual band pass filter)

The rapid spread of generative AI and the expansion of cloud services have placed data centers around the world in the midst of unprecedented levels of capital investment and technological innovation. The volume of data that needs to be processed continues to increase exponentially, and along with this, the heat generation, power consumption, and demands on communication bandwidth per server rack are becoming increasingly severe each year. Traditional electrical wiring for signal transmission faces physical barriers such as signal degradation and increased power consumption as transmission distances grow, leading to a rapid rise in expectations for technologies that utilize "light" as a solution. Optical communication, optical interconnects, optical sensing, and high-efficiency heat dissipation and shielding structures—many of these foundational technologies supporting data centers are deeply connected to optical thin films and the associated fine patterning processing technologies.

The home appliance and gadget industry is currently at a significant turning point. With the advent of IoT, all devices are now equipped with sensors and cameras, new wearable devices such as AR/VR devices and smart glasses are being launched into the market one after another, and smart home devices commonly come with displays and touch panels. Supporting the high functionality and added value of these products behind the scenes are optical thin film and patterning processing technologies. Suppressing lens reflections, optimizing sensor sensitivity, making fingerprints and dirt less likely to adhere, allowing current to flow while transmitting light through transparent conductive films—these are all achieved by forming functional thin films on the substrate surface at the nanometer scale and sometimes creating fine patterns. Trend 1: Miniaturization and high definition of sensor windows and optical thin films Trend 2: AR/VR, smart glasses, and anti-reflective and anti-fouling coatings Trend 3: Smart home devices and anti-fog, antibacterial, and self-cleaning functional films Trend 4: Integration of touch panels, transparent electrodes, and patterning processing The value that expert coatings can provide For more details, please visit our company website.

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 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

Light includes "visible light," which can be seen by the human eye, and invisible light. Near-infrared (NIR) is one type of "invisible light" located right next to visible light. In fact, it is deeply involved in various devices and industrial processes around us, and its importance has been increasing in recent years. We will explain clearly from the basics of "What is near-infrared?" to the fields in which it is used, and its relationship with optical coating technology. 01: What is near-infrared? — Organizing the "companions" of light 02: Where is near-infrared used? — Expanding application fields 03: The relationship between near-infrared and optical coatings — The power of "thin films" that enhance performance 04: The precision required for near-infrared filters Summary: The key to utilizing near-infrared lies in precise optical thin films Near-infrared compatible filter "Artisan Infrared" For more details, please visit our company website.
