カドミ光学工業 List of Products and Services

"Optical contact" is a technology that enables bonding by utilizing the attractive forces between materials without the use of adhesives. It is also referred to as optical bonding, and due to the absence of adhesives, it exhibits excellent properties not only in terms of heat and chemical resistance (such as strong acids and strong alkalis) but also optically. Creating a very closely approximated plane is crucial for this bonding, as it allows intermolecular forces to act and brings the glass substrates into close contact. Our company excels in the technology to create this bonding situation by leveraging precision grinding processes. Additionally, there is a method to further strengthen the bond through heating, which, unlike welding, maintains the smoothness of the glass surface, preventing refraction, absorption, and scattering of light.

This is an announcement for the "Kadomi Optical Industry Co., Ltd. Optical Glass Products Comprehensive Catalog." At Kadomi Optical Industry, we manufacture and sell a wide variety of optical components using materials such as synthetic quartz, Pyrex, whiteboard, BK7, crystal, and ClearCeram, including lenses, prisms, quartz parallel plane substrates, wedge substrates, rods, metal mirrors (Al, Au, Ag), dielectric mirrors, beam splitters, wave plates, polarization plates, quartz cells, micro flow cells, vacuum cells, fly-eye lenses, custom machined products, and glass tubes with polished inner and outer diameters. We accommodate production quantities from single prototypes to larger runs.

"Joining processing" finishes precision machine parts that are divided rather than processed as a single unit, achieving a fully mirror-like product through optical contact. It realizes surface precision and surface roughness that cannot be achieved by fire polishing. The material is quartz glass, which not only exhibits excellent optical properties but also demonstrates superior resistance to various stresses such as strength, heat resistance, and chemical resistance. Products utilizing our unique technology are expected to be applied in various fields in the future. [Features] - Polishing surfaces can be achieved even on the bottom and sides of recessed areas. - Concave surfaces (bottom surfaces) are finished with sharp right angles. - Excellent resistance to various stresses such as strength, heat resistance, and chemical resistance. *For more details, please refer to the PDF document or feel free to contact us.

We accept orders for the outer shape processing of glass substrates, lenses, and more. For example, we can accommodate requests such as "the specifications of optical elements are sufficient with commercially available products, but the dimensions are too large for installation in the device," "producing a prism or half-mirror as a single piece is too costly, so we would like to modify a commercial product," or "we want to shape a large filter into a circle to fit the holder dimensions." We can perform outer shape processing tailored to usability and specifications. In addition to offering products that include materials, we also accept processing of materials that customers already have. Please feel free to consult with us. 【Features】 ■ A variety of achievements in cutting and shaping processing ■ We can propose suitable processing methods according to the characteristics and specifications of glass ■ We can also cut and shape products according to other companies' standards, and we can handle tasks such as cutting out multiple substrates from a single material or shaping them. *For more details, please refer to the PDF document or feel free to contact us.

Our company has handled a wide variety of custom optical cells and optical contact products in small quantities. When joining the glass components of these products, precise material processing that minimizes chipping and other issues is essential. Leveraging this processing technology and experience, we can process glass—a material prone to chipping—at a high precision level while keeping chipping to an extremely small size. The main processing methods involve a combination of rotary grinding machines, Oscar polishers, and ring-type polishers. 【Features】 ■ Capable of processing glass surfaces to a high-precision flatness ■ Achieves the production of flat surfaces with extremely few scratches and rectangular blocks with chipping sizes minimized to the utmost through high-quality, high-precision polishing *For more details, please refer to the PDF document or feel free to contact us.

Our company is capable of various adhesive and joining processes through the fusion of advanced polishing and assembly techniques. Typical methods include UV bonding, frit bonding, and optical contact, with optical contact being particularly excellent in terms of optical and physical stress (heat resistance and strength), leading to the production of glass products and optical components in forms that have not been seen before. Please feel free to consult us when you need assistance. 【Joining Processing Technologies】 ■ Joining Processing - Optical Contact ■ UV Bonding ■ Frit Bonding *For more details, please refer to the PDF materials or feel free to contact us.
