Yes. We specialise in custom manufacturing according to customer-specific drawings and technical requirements. Each design is evaluated for manufacturing feasibility.

What information is required to request a quotation?

We preferably receive a technical drawing specifying the lens dimensions, spherical curvature, thickness and required optical surface quality. Information about the intended application and estimated annual quantities is also helpful.

What manufacturing tolerances can be achieved?

Achievable tolerances depend on the lens dimensions, curvature and surface quality requirements. Our engineering team evaluates each design individually to determine the achievable specifications.

What is the typical lead time for custom diamond lenses?

Lead times depend on the lens geometry, material availability, technical specifications and order quantity. An estimated delivery time is provided after reviewing your requirements.
