We respond to all requests, from mass production of general-purpose lenses to ultra-high precision polishing for stepper lenses!
We polish spherical lenses and prisms made of glass used in optical products such as vehicle-mounted lenses, projector lenses, and interchangeable camera lenses. Among the specifications required for glass polishing, the most significant evaluation item affecting the optical performance of the product is shape error. It is crucial to minimize the difference from the required shape within the effective range of the polished surface. In glass polishing, the processing conditions vary depending on the shape, glass material, and required precision, and it is necessary to discover the processing know-how for each lens. In particular, for cutting-edge spherical lenses used in objective lenses, an extremely high precision of λ/40 (approximately 16nm) is required. If the lens diameter is compared to the height of the Tokyo Skytree, the shape error is controlled with a precision comparable to the thickness of a one-yen coin. Examples of mass production processing achievements: - The outer diameter size of spherical lenses ranges from a few mm to 150mm. - Materials: In addition to regular glass, special glass materials such as soft fluorite and hard synthetic quartz can also be processed. - Surface accuracy: For an outer diameter size of φ150mm, λ/2 (approximately 316nm); for an outer diameter size of φ30mm, λ/10 (approximately 63nm); for an outer diameter size of φ5mm, λ/20 (approximately 32nm).
