Abstract

The invention relates to an observation device (10) for observing a method that generates metal vapours (55), the device comprising an observation means (11) and a protection device (13) that comprises a first shutter (14) and a second shutter (15) movable relative to the observation means (11), the first shutter (14) comprising a first opening (141) intended to be positioned in the field of view (CO) of the observation means (11) for a given position of the first shutter (14), the second shutter (15) comprising a second opening (151) intended to be positioned in the field of view (CO) of the observation means (11) for a given position of the second shutter (15), the protection device (13) comprising a drive means (16) configured to move the first shutter (14) and the second shutter (15) such that the openings (141, 151) are periodically and simultaneously positioned in the field of view (CO).
