Raw ODM98 blocks can be used for machining small size integrating sphere inserts, integrating sphere baffles, tubes, laser cavities, and other high reflectance parts. For cost effectiveness the size of the raw block should be as close as possible to the maximum dimensions of the final product. Custom size blocks can be ordered for larger quantity OEM orders. Custom size blocks are not available for prototypes or in small quantities. For small quantity orders Gigahertz-Optik stocks different size standard blocks for fast delivery. Contact our sales department to discuss your raw block requirements.
