カドミ光学工業 Product Lineup

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.

A "flow cytometer" can analyze the relative size and shape of individual cells, as well as their internal structures. The measurement method involves irradiating with an excitation laser at the measurement wavelength and performing fluorescence measurement. "Flow cytometer cells" require high standards in terms of dimensional accuracy, surface accuracy, and appearance level, and we supply products that meet these specifications. 【Features】 ■ Analysis of the relative size and shape of individual cells, as well as their internal structures ■ Fluorescence measurement performed by irradiating with an excitation laser at the measurement wavelength ■ High standards in terms of dimensional accuracy, surface accuracy, and appearance level *For more details, please refer to the PDF document or feel free to contact us.

The "light scattering particle counter" is a measurement device that irradiates a sample with light and detects the scattered light emitted from the particles in the sample. Our company manufactures the quartz flow cell, which is the heart of this device. Please feel free to contact us regarding optical cells. 【Features】 ■ Irradiates the sample with light and detects the scattered light emitted from the particles ■ Manufactures quartz flow cells *For more details, please refer to the PDF document or feel free to contact us.

The "spectroscopic gas cell" is a product designed for the high-precision measurement of absolute wavelengths. By filling the gas cell with a sample and transmitting light through it, the concentration of the target component is determined by measuring the light absorption caused by that component. Our company offers custom-made quartz glass gas cells suitable for use in the ultraviolet region. 【Features】 ■ Custom-made options available (Brewster window compatible) ■ Long optical path fabrication available (up to 500mm) ■ Window surface accuracy: λ/4 ■ Window surface quality: MIL40-20 *For more details, please refer to the PDF document or feel free to contact us.

At Kadomi Optical Industries Co., Ltd., we manufacture various optical assemblies tailored to meet our customers' needs. We have a track record of producing optical lens assemblies such as "relay lenses," UV adhesive "adhesive assemblies" for polarization plates, and the integration of lens systems and BS. Please feel free to contact us. 【Examples of Assemblies】 ■ Optical Lens Assembly: Relay Lens ■ Adhesive Assembly: UV Adhesion of Polarization Plates ■ Optical Component Assembly: Integration of Lens Systems and BS *For more details, please refer to the PDF materials or feel free to contact us.

Our microreactors are made using quartz materials, which not only allows for transparency but also enables the creation of flow paths with excellent laser light transmission properties and chemical resistance. Similar to optical cells, we combine polishing, bonding, and shaping techniques to meet various customer requests. In processing the flow paths, we can accommodate not only machining but also blasting and etching, allowing for the construction of complex flow paths that are not limited to straight or curved lines, such as spiral or star shapes. *For more details, please refer to the PDF document or feel free to contact us.

The term "glass container / optical cell" refers to a container used to store samples such as liquids and gases, and to conduct analysis through light transmission and absorption. As mentioned earlier, it is optically bonded (joined without the use of adhesives) which makes it resistant to chemical elements such as acids and alkalis, as well as to high and low temperatures, allowing for various applications. It can flexibly accommodate specifications for small-scale production and custom orders. 【Features】 ■ Resistant to chemical elements such as acids and alkalis, as well as to high and low temperatures ■ Usable for a variety of applications ■ Flexible support for specifications regarding small-scale production and custom orders *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 utilizes advanced glass polishing and machining processes to manufacture a variety of glass products. We can process high-purity quartz glass, which has high transparency and stability, with high precision, allowing us to produce components with excellent dimensional accuracy and optical properties. We have also achieved optical contact (a strong bond without the use of adhesives), enabling the production of parts with shapes and precision that were previously thought to be difficult to achieve with glass products. By creating tools with minimal fluctuations due to temperature changes, we can leverage the transparency of glass for visualization, contributing to improved accuracy and efficiency in visual inspections. In particular, products with optical contact do not use adhesives, eliminating absorption and scattering caused by adhesive layers, and there is no shrinkage or thermal expansion, allowing us to produce high-precision and high-quality components. While it may seem that machining holes, grooves, and screw holes in glass materials, which are hard and brittle, is difficult, there are many cases where it can be addressed with clever engineering.
