Isuzu Glass participates in joint development with Kyoto Institute of Technology, Osaka Univ, Shiga prefecture Univ, Hokkaido Univ and The National Institute of Advanced Industrial Science and Technology (AIST). We pursue the refinement of our core technology "Glass melting" and "Molding technology" and look for innovative ways to advance our technology to fulfill new business fields.

Double-sided molded lens

double-sided molded lens

* This is a prototype 3D model. If you drag the model with the mouse, it will rotate according to the movement of the mouse. You can also zoom in / out the model by scrolling the mouse wheel.
We are developing a double-sided lens array integrally molded,which was previously manufactured by laminating. Since it is not bonded, the adhesive does not burn due to a high power light source such as laser. We can achieve optical axis tolerance of ± 0.05 mm, comparing present laminated lens tolerance of ± 0.1 mm. Both prototyping and mass production is OK for us.

Moldable UV Transmitting Glass IHU250H


A new product, IHU250H, has been added to the IHU Series of UV transmitting glass.
This product can transmit shorter wavelengths of UV light than the previous product. It has excellent workability and can be used not only as a glass material for molding but also for metallizing. In response to the high demand for glass in the ultraviolet region, we are developing glass that can transmit even shorter wavelengths of ultraviolet light than the IHU250H.

Infrared Transmitting Glass (IIR-SF Series)

IR-SFR1 is the glass consisting mainly sulfur and has good transmission in infrared range.This glass is particulaly useful for cameras and sensors that operate up to 11μm. Furthermore, it is less expensive than crystals of germanium, etc., which are widely used at present.
We are currently streamlining the mass production system of chalcogenide glass that contains no harmful substances such as arsenic and selenium specified by the RoHS directive and REACH. Furthermore, we are developing IIR-SFR2 which outperforms conventional IIR-SFR1. We are planning to develop the composition according to needs to increase the repertoire of products in the future.

Laser Glass

Laser Glass

We developed a High Power Laser Amplification Glass.
We built a melting facility that supply Pt particulate free glass and can supply glass following your specifications.

Battery Materials

Battery Materials

We are currently developing negative electrode materials for all-solid batteries that are considered to be most likely to be post Li-ion secondary batteries in the joint research with Technology Research Institute of Osaka Prefecture. Our negative electrode materials are being developed through the application of high-quality chalcogenide glass that has been successfully developed so far.

Hybrid Materials (Glass + Plastic)

Hybrid Materials

Based on our long-term achievements in the manufacture of optical glass absorption filters, we have succeeded in the development of the materials that enable flexible molding at low costs by maintaining the absorption performance derived from glass properties and making the best use of resin formability.
