METHOD FOR OPERATING AN OPTICAL APPARATUS, AND OPTICAL APPARATUS
A method for operating an optical apparatus (100A, 100B, 200), having a structural element (201) which is arranged in a residual gas atmosphere (RGA) of the apparatus and which is formed at least partly from an element material subjected to a chemical reduction process and/or an etching process with...

| description | A method for operating an optical apparatus (100A, 100B, 200), having a structural element (201) which is arranged in a residual gas atmosphere (RGA) of the apparatus and which is formed at least partly from an element material subjected to a chemical reduction process and/or an etching process with a plasma component (PK) present in the residual gas atmosphere includes: feeding (S2) a gas component (GK) that at least partly suppresses the reduction process depending on a detected suppression extent (UM) for a suppression of the etching process and/or reduction process by the suppressing gas component in the residual gas atmosphere; and detecting (S1) the suppression extent with a sensor unit (208) arranged in the residual gas atmosphere. The sensor unit includes a sensor material section (211) composed of a sensor material and exhibiting a sensor section property that is measurable under the influence of the suppressing gas component. |
