Cold mirror: A filter that transmits near-infrared light and reflects visible light.

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.

Among optical components, metal mirrors possess characteristics such as "broadband and stable reflection performance," "minimal variation in properties with respect to incident angle," and "excellent durability," making them a crucial factor that influences the reliability of devices. They can cover not only visible light but also infrared (IR) and even ultraviolet (UV) regions, leading to their widespread adoption from fundamental research to industrial applications. In this article, we will thoroughly compare the types of representative metal mirrors and their features, clearly organizing selection points based on applications and purposes. We aim to provide helpful information for those wondering, "Which metal is best suited for my device?" 1. The mechanism of metal mirrors and representative coating materials 2. Evaluation criteria for major metal mirrors 3. Aluminum mirrors (Al) 4. Silver mirrors (Ag) 5. Gold mirrors (Au) 6. Aluminum enhanced mirrors (Al Enhanced Mirror) 7. Recommended metal mirrors by application (selection guide based on technical background) 8. The added value that Adachi New Industry can provide (technology + proposal capability)

Modern advanced technology relies on precisely manipulating parameters such as the wavelength, direction, and intensity of light. At the center of this light control is the optical mirror. The basic function of an optical mirror is to reflect incident light in a specific direction with high efficiency, but it goes beyond being just a reflective surface. Depending on the application, advanced optical performance is required, such as "which wavelengths to reflect or transmit," "how much reflectivity to achieve," and "how accurately to focus and form images." - The role and importance of optical mirrors - The two main types of mirrors: metallic mirrors and dielectric mirrors - Metallic mirrors: basics and characteristics of reflection - Dielectric mirrors: technologies that achieve high reflectivity - Comparison table: contrast between metallic mirrors and dielectric mirrors - Specific examples of differentiation based on applications - Summary and outlook: the importance of technology selection and contributions to industry For more details, please visit our company website.
