Frequently Asked Questions
Q: How to choose between molding and polishing for aspherical lenses?
A: Molding is suitable for high-volume production (diameter <30mm) with good consistency, but requires mold tooling upfront. Polishing is suitable for small-batch samples and R&D with a wider size range (up to 120mm), no mold required, offering greater flexibility.
Q: What is the minimum diameter available?
A: Polishing can go down to 15mm diameter; molding is available for diameters under 30mm. Please contact us for smaller sizes.
Q: What materials are available for custom aspherical lenses?
A: Materials can be customized upon request, including optical glass, infrared materials, etc. Please provide material type or specifications.
Q: What is the precision level of <5 arc minutes eccentricity?
A: 5 arc minutes is a typical eccentricity tolerance for most imaging and inspection systems. Higher precision is available upon request.
