Multi-band pass filter (dual band pass filter)

In the medical and healthcare fields, light has already become an indispensable infrastructure. From endoscopes, fluorescence observation devices, blood analyzers, pulse oximeters, and wearable vital sensors to regenerative medicine and phototherapy devices, optical control technologies such as "wavelength selection," "reflection control," "stray light suppression," and "high-sensitivity detection" are required in every scenario. However, in actual design settings, it cannot be said that there are many cases where equipment manufacturers and optical thin film manufacturers engage in sufficient discussions from the early stages. As a result, filters and mirrors are often "added later" in the optical system's post-processing, leaving room for improvements in S/N ratio, miniaturization, and low power consumption that should have originally been achieved. We will redefine the role of optical thin films in the medical and healthcare fields and explore the possibilities from the perspective of "functional co-creation" rather than just "material supply." 1. The essence of wavelength design in biosensing 2. How reflection and absorption control change the image quality of endoscopes and observation systems 3. Wearable medical devices and angle-dependent design 4. High-durability thin films in phototherapy and sterilization fields The option of co-creation - a proposal from Adachi New Industry Co., Ltd.

We have added a standard stock lineup for the "bandpass filters using colored glass," which has been frequently inquired about! If you are considering a 900nm bandpass filter, please feel free to utilize it. This product is designed to maintain a consistent transmission rate even when the angle changes, and the waveform remains stable even if the angle is misaligned, thanks to the use of colored glass. ◆ About standard stock items from Adachi Shin Sangyo Co., Ltd. .. - I need a few pieces at different levels for urgent product development and performance testing... - I want to try a rough estimate for now... - I would like to make a slight change in shape for prototyping... Adachi Shin Sangyo sincerely addresses the voices of such customers! In today's world, where simulation technology has advanced, we will respond quickly to customer requests by providing standard stock items, so please feel free to contact us!

The Kansai Expo is being held as an international event where cutting-edge technologies, services, and cultural expressions from around the world gather under the grand theme of "Designing a Future Society Where Life Shines" (as of the article dated September 29, 2025). From AI-driven autonomous robots and next-generation mobility to immersive video experiences, space exploration technologies, and future medical and healthcare innovations, a wide range of innovative technologies are being showcased right before the eyes of visitors, providing a valuable opportunity to experience the vision of society's future up close. In our series, we have focused on optical thin films and fine pattern processing (metallization) technologies, which function as the unsung heroes behind these cutting-edge technologies, introducing them over seven installments. Optical thin films enable precise light control, such as reflection, transmission, and wavelength selection, playing an essential role in various advanced devices like sensors, cameras, projectors, and space equipment. Meanwhile, fine pattern processing serves as a foundational technology that supports the high precision of electronic devices, biosensors, and next-generation displays by controlling structures at the nanometer level.

During the 2025 Osaka-Kansai Expo, I had the opportunity to experience Kawasaki Heavy Industries' quadrupedal personal mobility product "CORLEO." I must honestly say that I was "quite shocked" by its innovative and advanced technology. It stimulated our engineering spirit and ignited a strong curiosity to understand more deeply and explore the essence of the technology. For this reason, I would like to reconsider through this article how future personal mobility will evolve and how our optical thin film technology can be involved. With a humble heart and a slight sense of confusion, this marks the beginning of a journey to explore future possibilities. [1] The concept of mobility instinct [2] What is CORLEO? [3] Technical features and innovations [4] Speculations on the optical components that will be installed Conclusion - Prospects for practical application For more details, please visit our company website.
