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
