MANUFACTURE OF PART, MATRIX USED FOR METHOD AND MANUFACTURE OF MATRIX

摘要

A method of manufacturing components such as optical components (17, 18, 21, FIG. 2C) by means of a matrix which comprises a preform 12 of glass or quartz and has a skin 14 of a cured epoxy synthetic resin, the surface of which is the negative of a metal mold from which the matrix is produced. The matrix is suitable for use in the above-mentioned method, whereby optical components are produced which have surfaces that are for example, the aspherical negatives of the matrix surface.
