カドミ光学工業 Product Lineup

Especially recently, due to advancements in microfabrication shifting towards shorter wavelengths, our company has also been producing fly-eye lenses using synthetic quartz lenses. Additionally, they are used on the projection light side of LCD substrates in LCD projectors.

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.

The "Fly Eye Lens" is an imaging element that arranges the same single lens in both vertical and horizontal directions. By passing light output from a fiber laser through this product, it is possible to create the same conditions as a multi-point light source, enabling uniform illumination. Additionally, each lens is joined using a unique technique after being polished. Coatings with high transmittance and durability in the ultraviolet range are also available. It is mainly used in the illumination systems of semiconductor exposure equipment. 【Processing Specifications】 ■Outer Diameter: Up to 420mm ■Number of Elements: Up to 200 ■Material: BK7, Quartz Glass ■Lens Shapes: Plano-convex Lens, Biconvex Lens, Drum Lens ■Adhesion Method: Frit Adhesion, UV Adhesion *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.

The "Light Guide" can output light as uniform illumination on the irradiation surface by reflecting the light emitted from a fiber laser within a rod or light pipe. It is a hollow type assembly with a reflective film applied to the inner surface of the substrate, compatible with shapes such as square, round, hexagonal, and tapered. 【Processing Specifications】 ■ Material: BK7, synthetic quartz ■ Outer dimensions: □1mm to □30mm ■ Length: up to 300 ■ Surface accuracy: optical polishing up to λ/20 ■ Parallelism: 5 seconds or more ■ Effective diameter: within 90% of the actual size *For more details, please refer to the PDF document or feel free to contact us.
