Custom Optics & Capabilities Resources Use our helpful tools, guides, videos and other resources to solve your optical design challenges. These meticulously crafted optical components function by leveraging the dispersion properties of distinct glass materials to achieve near-perfect collimation of specific wavelengths across the visible spectrum. Centration to seconds Broad range of materials including optical glass (Schott, Ohara, Hoya, CDGM), fused silica, fused quartz, filter glass, and float glass. Optical engineering through manufacturing What is an achromat? An achromat combines a convex lens and a concave lens, often made with different materials with different refractive properties, to focus light to the same spot, correcting for chromatic aberration and resulting in a sharper image. You'll be assigned a LaCroix Manufacturing Engineer dedicated to seeing your project from sketch to completion. We follow a step-by-step process with rigorous quality checks along the way. 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 In-House Custom Optical Coatings We have extensive in-house coating capabilities to meet your requirements. Looking to learn more about achromatic lenses? Use our resources.
