Advantages of Custom Azylinders

Superior surface quality

Based on the specially developed technology for CNC grinding and polishing processes, asphericon is able to produce acylinders with minimal surface form deviations (RMSi ≤ 0.05 µm). Matching your individual requirements, we manufacture high-quality acylindrical optics of highest accuracy with best imaging properties.

Ideal line-focus without spherical aberration

Aspherical cylinder optics have a focus line instead of a focal point due to their geometry. Free of spherical aberrations, best optical imaging qualities can be achieved. Benefit from the unique accuracy and precision of asphericon's customized acylinders.

Uncoated and with high-quality coatings

For a maximum optical radiation output, we offer the possibility of refining acylinders with high-quality coatings. From anti-reflection to metallic layers and wavelength-specific filter coatings, we coat in-house with reasonable delivery times.

Complementary Services

In addition to high-quality coatings, asphericon's reliable service also includes optical measurement for maximum effectiveness and longevity of your optics. Convince yourself of the high accuracy of our measuring systems. For a simple combination with other mounted optical components, we will be happy to add a high-quality mount to your optical components.
