Abstract: The present invention defines an optical polishing lap comprising a thermoplastic polymer resin of uniform density, porosity, and texture throughout including the surface of the lap. The optical lap is of unitary construction formed having a solid main body with a generally domed-shaped upper head portion of substantially monolithic form providing an upper curved surface. The optical lap includes a lower flat surface having an attachment means defining an integral base portion extending downward opposite the lower flat surface offset from the main body. The integral base portion defines webbing having a continuous peripheral rail extending around the edge.
