Isuzu Glass

What Isuzu Glass does

Isuzu Glass Co., Ltd. (株式会社五鈴精工硝子) is a Japanese precision optical components manufacturer headquartered in Izumisano, Osaka, with a Tokyo sales office and a wholly-owned US subsidiary, ISUZU GLASS, INC., in Torrance, California. The company produces optical glass filters spanning UV, visible, and IR wavelength ranges alongside glass molded lenses that include aspheric lenses, integrated and micro lens arrays, double-sided molded lenses, and atypical shaped lenses. Its principal technical differentiator is in-house glass melting, which enables proprietary compositions such as moldable UV-transmitting glass (IHU250H, IHU200, IHU200LM) and opal glass diffusers (IOP010, IOP200) that are difficult for thin-film filter makers to replicate. Secondary offerings include UV water sterilization modules, high-density IR absorbing filters, laser protective goggles, optical wireless power transmission lens arrays, sintered quartz lenses, large-diameter spherical lenses up to 1100mm, and specialty prisms. All filters are RoHS and REACH compliant.

The company serves B2B industrial clients in exposure equipment manufacturing, medical devices, sensors and laser optical systems, and UV sterilization, with vertical segmentation across these four end markets. Revenue is generated through one-time hardware sales of catalog and custom optical components and through professional services covering optical design, custom glass melting, and precision processing; pricing is quote-based with no public disclosure. Marketing is sales-led, relying on international trade show participation (BIOS & Photonics West, Laser World of Photonics, OPIE, interOpto, VISION) and downloadable technical documentation in Japanese, English, and Chinese. Geographic reach is supported directly in Japan and the United States and through partner enterprises KISCO (Taiwan), KISCO TRADING (Shanghai), and ISUZU OPTICS CORPORATION (Taiwan).

Isuzu Glass is privately held with no disclosed funding rounds, institutional investors, or revenue figures, and no evidence of public listing. The firm was recognized as an Indispensable Long-established Company of Kansai 2026 and announced a change in Representative Director and President on May 1, 2026, marking the most recent material corporate event in the available record.
