Precision Optics Manufacturing

The selection of an optical material is a critical engineering decision driven by the specific requirements of an application, including the operational wavelength, thermal environment, mechanical durability, and cost. While a vast catalog of materials exists, they are typically chosen based on a combination of key optical and physical properties. At Schneider-Kreuznach, our expertise lies in selecting the optimal material to ensure the final system performs reliably and meets all specifications.

Ensuring surface quality is a multi-faceted process that goes far beyond a simple final inspection. It is a core tenet of our manufacturing philosophy, achieved through a combination of meticulously controlled fabrication processes, continuous in-process metrology, and comprehensive final qualification. The quality of an optical surface directly impacts critical system parameters such as image contrast (via scatter), system throughput, and laser damage threshold.

In optical manufacturing, "tolerance" refers to the permissible limit of variation for a given physical dimension or optical property. The process of setting these tolerances is a critical part of the engineering phase, representing a crucial balance between the desired system performance and the cost and feasibility of manufacturing. Tighter tolerances invariably lead to a more complex and costly manufacturing process. Therefore, at Schneider-Kreuznach, we work closely with our clients to establish a tolerance budget that meets the application's performance goals without unnecessary over-specification.
