AII 7-axis Asphere Robotic Polisher

The AII pre-polishes the ground blank before corrective and finish polishing using Precessions software. The Precessions technique creates a circular polishing spot, which traverses the surface of the optic in either a spiral or raster pattern. The spot's removal function has a Gaussian footprint. Using this regular shape, the software computes a tool control function first to predict and then to perform rapid corrective polishing using the variables of dwell time, spot size and tool pressure. This software optimizes form-correcting tool path data based on an error map that has been computed from design data and metrology information. Metrology data may be imported from the LOH TII Topography Measuring device as well as commonly used instruments from Veeco/Wyko, Zygo and Taylor Hobson. According to LOH, other interfaces can be prepared on request.

This robotic polisher produces aspheres from ground or pre-polished components -- including glass, ceramics, crystals, suitable metals, semiconductor materials, composites and others.
