Superior Performance for High Precision Optics
Optimax offers integrated manufacturing and measurement capabilities to produce precise, complex
shapes that can replace multiple elements for lower weight and improved end-product performance.
We utilize deterministic CNC machine tools for predictable removal rates and adherence to tight
tolerances. Precision tools constrain the aspheric axis to conserve centration.
By investing in the most advanced technology, we can offer/ensure the widest array of manufacturing
options and best quality end product.
Materials:
Glass, fused silica, crystals, ceramics
