Pitch polishing is a similar concept to the lapping process except it is using a pitch plate and much finer polishing media.
Lapmaster manufactures and uses single-sided polishing machines for a variety of optical components, i.e. optical flats, filters, prisms and for the refurbishing of customer’s optical components.
Typically, components range in size from 20mm diameter to 600mm diameter. Other sizes are achievable depending on both machine and component size and type.
Significant skill is required for pitch polishing, achieving tighter tolerances for surface flatness, roughness, parallelism and cosmetics than you would achieve using the conventional lapping process with coarser abrasives.
The pitch polishing process also produces a significantly improved surface quality with a typical Ra of less than 5 Å.
Pitch plates are a semi-fluid surface with a consistency similar to bitumen (asphalt) and are manufactured at our UK site. Concentric, spiral, radial and cross-hatched grooving is either hand cut or machine cut to allow the polishing slurry to flow beneath components, resulting in exceptional surface roughness and surface flatness.
The highly-experienced optical technicians at Lapmaster have extensive knowledge and experience of the optical polishing process and can provide consistent, high quality components.
Typical Optical Polishing Manufacturing Limits on our Lapmaster 48 Air Bearing Machine:
|Diameter||≤ 300mm Optical Reference Flat|
|Surface Roughness||≥ 5 Å rms|
|Cosmetics (scratch/dig)||60-40 to 10-5|
Cerium Oxide (CeO2) offers an enhanced polishing performance for optical flats, as well as other applications like filters and prisms. Cerium oxide has long lasting polishing efficiency providing excellent surface quality. Cerium oxide can retain its effectiveness over longer periods, even when used under demanding polishing conditions. It’s used for optical pitch applications and with a variety of pads. This abrasive is used strictly for polishing glass like materials on a soft polishing pad or pitch polishing plate. The average particle size utilized is typically somewhere in the range of one to three microns. Some brands of cerium oxide have a slightly high pH level. These abrasives cause an oxidation of the surface being polished. The oxidized material is mechanically removed by the rotating action of the pitch plate or polishing pad.
Polishing machines utilizing cerium oxide abrasive slurry should be protected from corrosion by using stainless steel components and epoxy paints. The water most commonly used with the cerium oxide is also a source of corrosion for unprotected ferrous metal machine components. The standard Lapmaster Wolters pitch polishing machines are constructed appropriately to eliminate corrosion problems from contact with water and high pH abrasive. It is important to consider this issue whenever quoting a standard lapping machine that is modified for cerium oxide polishing.
