Abstract
A method and apparatus for manufacturing optical components. A burner generates soot, and a surface area collector collects the soot. The burner is disposed such that the soot collected within the surface area collector is substantially not reheated by subsequently deposited soot. Magnetic forces direct the soot to desired location(s) within the surface area collector. The surface area collector operates at relatively low temperatures sufficient to retain rather volatile substances, such as fluorine, in the soot.
Claims26
A method for manufacturing soot used in fabricating an optical component, the method comprising the steps of:
- generating the soot via a burner having a flame that produces heat, the burner having a temperature of greater than 1000° C. associated therewith;
- collecting the soot at a surface within a surface area collector, the surface having a temperature of less than 500° C. associated therewith.
