We will be exhibiting at interOpto2025 / Light and Laser Science and Technology Fair (Ultraviolet Fair).

"IHU250H" is a moldable ultraviolet-transmitting glass that can be processed at lower temperature ranges compared to quartz and has a thermal expansion rate close to that of metals.

Product Introduction: IHU250H The "IHU250H" is a glass that functions as an optical glass filter that transmits ultraviolet light, while also being usable as a molding material. Its lower processing temperature compared to quartz and thermal expansion rate closer to that of metals make it suitable for metallization. For detailed optical properties, please refer to the downloadable materials. Features ■ Processing temperature range is lower than that of quartz (1600-1700°C) (IHU250H: 563°C) ■ Thermal expansion rate is closer to that of metals than quartz, making it suitable for metallization ■ Available for sale as molding materials such as block materials, rod materials, and ball lenses.

Diffusion glass "IOP series" that enables uniform light diffusion and transmittance adjustment.

【Product Introduction: IOP Series】 This is a diffusion glass that uniformly diffuses incident light and has characteristics close to a Lambertian light source. The milky white color is due to the glass itself, not an opal coating. It has higher diffusivity than frosted glass. A feature of this product is that the spectral transmittance can be adjusted by changing the thickness. 【Features】 ■ Uniform diffusion glass close to a Lambertian light source ■ Higher diffusivity than frosted glass diffusion plates ■ Transmittance can be adjusted by modifying thickness and manufacturing conditions ■ Ideal for optical applications in machine vision, LED lighting, and observation systems

Consistent production through innovative technology from prototype to mass production.

**Product Introduction: Glass Molded Lenses** Glass molded lenses, created through die-casting molding, achieve complex shapes that are difficult to produce through polishing, as well as lens structures that previously required assembly, all in a single molding process. Most products are fully customized according to customer requests. We can flexibly accommodate everything from prototypes to mass production. In addition to the lens molding technology we have cultivated over many years, we utilize our unique measurement and inspection techniques to provide high-precision products. We cater to a variety of shapes and specifications, including not only lens arrays but also aspherical lenses, Fresnel lenses, rod lenses, and irregular lenses. **Features** ■ Integrated glass lenses through molding ■ Achieves complex shapes and integrated structures, enabling shapes that are difficult to polish ■ Fully customized support from prototype to mass production ■ Proven track record with various shapes including aspherical lenses, Fresnel lenses, rod lenses, and irregular lenses ■ High quality guaranteed through unique measurement and inspection technologies

[Speaker] Masatoshi Fukuda, Director of the Management Planning Office, Tokyo R&D Corporation [Key Lecture Content] Focusing on next-generation mobility (robot taxis, buses, trucks), this lecture will organize the evolution of technologies and services in various fields based on reports from major exhibitions in Europe and the U.S. and experiences from actual vehicle test rides, following the flow of "overall picture → individual cases → insights," providing an overview of the latest trends. It will cover electrification (EVs, FCEVs, etc.) and the related technologies that support it, as well as the trends in vehicle, software, and sensor technologies for autonomous driving, sharing the changes observed in the field in Europe and the U.S., including new forms of public transportation services (operational forms and service content). [Lecture Items] 1. Introduction 2. ACT (Advanced Clean Transportation) EXPO 2025 Inspection Report 3. UITP Global Transport Summit 2025 Inspection Report 4. Busworld 2025 Inspection Report 5. Introduction of Autonomous Vehicles at CES 2026 6. Robot Taxi Test Ride Report 7. Q&A / Business Card Exchange

We held a preview event for our newly released latest device, "Micral." Micral is a next-generation solution equipped with the latest LIBS technology (Laser-Induced Breakdown Spectroscopy), achieving both "significant simplification of sample preparation" and "overwhelming analysis speed." It accommodates a variety of samples (matrices) such as food, feed, and dairy products, bringing innovation to on-site analysis operations. We wanted you to directly experience the operability and speed of Micral, so we invited customers to bring their own samples for measurement during this event. We hope that this can serve as a hint for improving the efficiency and safety of your analysis operations and be considered as one of the factors in your future equipment selection.

If production and logistics are managed separately in the factory, it can lead to negative consequences. This is the "key point of logistics improvement." For example, standard work instructions, standard times, and productivity management. What is normally done in the production process is not implemented in logistics. As a result, logistics can become a bottleneck, and it is not uncommon for the overall efficiency of the factory to decline. Why is "in-house logistics" important now? The government is promoting the optimization and efficiency of logistics as a social theme, and as part of this, the establishment of "logistics coordinators" is beginning to be required, starting with large businesses. It is predicted that this will eventually spread to medium and small enterprises as well. It is necessary to start improving in-house logistics now and to establish a strategic logistics management system. This course will lecture on what in-house logistics should do to achieve "overall efficiency of the factory." There is an order to logistics improvement. By incorporating exercises and thinking together, as well as discussing together, please internalize the methods for improving in-house logistics. *For more details, please download the PDF or contact us.
