1. Optical Design

Collaborate with our engineers to verify your print. We'll work with you to recommend the right optical material for production.

2. Crown and Flint Manufacture

We'll use a lower dispersion material for the convex crown, and a higher dispersion material for the concave flint.

3. Optical Alignment and Assembly

After precision alignment in both the optical and mechanical axis, lenses are cemented together using a specialized index-specific optical cement. The optical cement is then cured using UV light.

4. Centration

After assembly, some of the doublets are centered to the final diameter while others are pre-centered before cementing. Doublets can also be blackened after assembly to reduce scattering, which can be beneficial in some optical applications.

5. Test and Measurement

Interferometry, surface roughness, radius of curvature, aberrations, and more.
