摘要

An optical observation instrument has a device (1) for protecting against incoming flare (40) arranged within the beam path of the instrument. The device contains a filter (22/30) tuned to the flare (40). The filter (22/30) is configured and arranged within the beam path such that the flare (40) transits the filter (22/30) at least two times.
