<p>A method and apparatus (20) for manufacturing optical components. A burner (24) generates soot (22), and a surface area collector (26) collects the soot (22). The burner (24) is disposed such that the soot (22) collected within the surface area collector (26) is substantially not reheated by subsequently deposited soot (22). Magnetic forces (50) direct the soot to desired location(s) within the surface area collector (26). The surface area collector (26) operates at relatively low temperatures sufficient to retain rather volatile substances, such as fluorine, in the soot (22).</p> |
