"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. Please feel free to consult us when needed. *For more details, please refer to the PDF document or feel free to contact us.*

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.
