Multi-band pass filter (dual band pass filter)

In recent years, "STEAM education" has rapidly spread in educational settings, increasing the importance of experimental environments and measurement technologies for experiential learning in science and technology. Among these, spectroscopic techniques that analyze substances and environments using light have gained attention. Not only in cutting-edge research fields such as spectroscopic measurement, laser experiments, and biosensing, but also in universities, technical colleges, and high schools, there has been an increase in experiments utilizing optical technologies. The foundation of these technologies is optical thin films (optical filters) that control the wavelength of light. Optical thin films significantly improve the accuracy of spectroscopic measurements and optical sensing by allowing only specific wavelengths to pass through or by blocking unwanted light. Furthermore, they hold potential as educational materials that enable intuitive understanding of the physics of light through phenomena such as interference and structural colors. 1. Compatibility of STEAM education and optical technology 2. Optical thin films used in education and research fields 3. Custom optical thin films required for research applications 4. Potential of optical thin films as educational materials 5. Co-creation proposal: New initiatives with educational and research institutions Optical thin films are materials that connect "learning" and "technology."

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.

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...
