Abstract
A new compliant sub-aperture optical finishing technique is being investigated for the removal of mid-spatial frequency artifacts and smoothing of hard polycrystalline infrared ceramics for aspheric applications and conformal shaped optics. The UltraForm concept was developed by OptiPro Systems, Ontario, NY, and is a joint process development effort with the Center for Optics Manufacturing (COM). The UltraForm tool is a pressurized, elastomeric bladder in the shape of a toroid. Finishing pads are attached to the periphery, allowing the use of a wide variety of pad materials and abrasive selections. Experimentation has been conducted using both slurry mixes and fixed abrasive pads. The toroidal tool is rotated while the compliant tool is compressed into contact with the surface. Currently this process has specific interest for the finishing of conformal ALON domes. Also to be discussed will be new versions of the UltraForm Tool, which are currently being developed and tested.
