Abstract:
    A visibility appearance debugging optics attenuator using for visibility appearance testing and debugging belongs to atmosphere optics field. It relates to single optics radiation attenuation plant or optics radiation attenuation plant group made by more than one optics radiation attenuation plants and engine drawtube. One ending of the engine drawtube sets with interface to be added to the optics receiver components of the visibility appearance, and the optics radiation attenuation plant or optics radiation attenuation plant group assembles in the engine drawtube. It resolves the problem that cannot nicety adjust instrument for the weather and has practicality value under the bad weather. It satisfies different circumstance request and correlative testing equipment with wide market foreground and great economy meaning.
