Hi M,
Not only will the sensor design and any coverglass potentially limit performance in to the UV, but the scope or lens will also limit UV performance
below about 350nm. There are some optics that can reach down to about 300nm and some very expensive specialist UV lenses that approach 200nm.
Best
