Special optical components

Components and customer-specific assemblies for the harshest environmental conditions

In many medical and industrial applications, components are required for light splitting, switching, or beam formation. Our special optical components have been truly tried and tested in a huge variety of disciplines, sometimes under the very harshest of conditions. Whether for space exploration, aggressive industrial environments, or extreme temperatures, LEONI develops exceptional solutions and components for exceptional use cases.
