Technical properties of the OMF ion beam figuring system
- Surface qualities of λ/200 and greater possible (depending on measurement system)
- Starting precision of one lambda @633 nm is sufficient
- Each machine is fitted with a 6-axis direct drive system, so that the ion source is always at a right angle (orthogonal) position to the workpiece surface
- Processable shapes include: flat, spherical, aspherical, freeform, off-axis aspherical, acylinders, prisms, axicons and others upon request
- Processing across the entire surface up to and beyond the edge
- All processing movements are possible (meandering, spiral shaped, freeform, etc.), without changing the machine set-up
- All mono-crystalline, amorphous and metallic materials can be processed. Examples: all kinds of optical glasses, quartz glass, Zerodur, ULE, KDP, sapphire, Si, SiC, Ge, etc.
- Completely stable processes that are externally reproducible
- Each machine has a main chamber and a lock chamber, which makes changing workpieces quicker
- Automatic integrated diaphragm changer for various ion beam diameters of 0.5 to 20 mm (optionally available)
- Fully automated process, iterative process workflow, without workpiece measurement between processes with different diaphragm openings, process expanded with robots and placing systems for fully automated processing of multiple different workpieces (optionally available)
- Real-time measurement for determining the ion beam etching rate within seconds, without the need for a separate workpiece sample (optionally available)
- Low operating costs and low maintenance requirements
