Infrared reflection prevention film: A filter that efficiently transmits the wavelength range of 9μm.

Even in the current era of accelerating digitalization, stationery and office supplies remain indispensable to our work and learning. Not only traditional products like notebooks and writing instruments, but also electronic whiteboards, tablet devices, conference systems, digital signage, and authentication cards are becoming increasingly advanced in office spaces year by year. In particular, recent market changes such as hybrid work, the ICT transformation in education, the development of smart offices, enhanced information security, and the introduction of sensing technologies have made "visibility," "usability," and "information reading accuracy" significantly influence product value. Among these, the technology for "controlling light" has begun to attract attention. 01: Stationery and office supplies are becoming "information devices." 02: AR coatings change "visibility" and "ease of work." 03: The evolution of digital stationery and sensing technology. 04: New possibilities for "attractive stationery" and optical thin films. Summary: The next stationery and office supplies will be differentiated by "light." For more details, please visit our company website.

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.

The areas where drones are active are rapidly expanding from surveying, infrastructure inspection, agriculture, logistics, and disaster prevention to defense and security fields in recent years. In addition to the demand for high-precision sensing in the private sector, the requirements for optical systems mounted on drones are becoming increasingly stringent in defense applications such as border surveillance, information gathering, search and rescue, and unmanned operational support. While the miniaturization and weight reduction of the aircraft are progressing, the proposition of "obtaining more precise information in harsher environments" remains unchanged. One key to solving this contradiction is optical thin film technology. Optical thin films, which control the reflection, transmission, and blocking of light at the nanometer level, are a technology that fundamentally enhances the performance of mounted sensors across the visible light, near-infrared, and thermal infrared ranges. We will introduce the role that optical thin films play in drone development from the perspectives of industry, agriculture, and defense. 1. What are optical thin films? — Basic knowledge for drone developers 2. By field: The roles played by optical thin films 3. Featured technology: 8-14μm band infrared AR coating 4. Quick reference table for utilization images by development phase 5. Proposal for co-creation — Let's start together from a prototype For more details, please refer to our company website.

"We will provide a thorough explanation of infrared windows!" has been added to the technical trend keywords. Optical windows used in the far infrared region (8-14μm) for infrared sensors, thermography, CO₂ lasers, and NDIR gas analysis require a balance of transmittance, environmental resistance, manufacturability, cost, and supply stability. In other words, it is a component that requires multi-axis evaluation of "optical performance × environmental resistance × manufacturability × economic viability × procurement capability," and selecting the optimal material according to the application influences the product's performance, reliability, and cost competitiveness. 1. The technical importance of far infrared windows 2. Optical properties and selection guidelines for representative far infrared window materials 3. What are the typical applications? 4. Trade friction and material availability: supply risks and trends in domestic production 5. A bridge to stable supply and future markets For more details, please check our company website.
