Even in the few cases where the UV filter might have protected the front element, the lens was dead anyway. Since sensors are much more sensitive to visible and IR light compared to UV, the out of band signal needs to be blocked VERY strongly. Other variations of UV filters available from filter manufacturers include UV17, which eliminates approximately 97% of the ambient UV, UV-410 for high-altitude and open-water environments and UV-420, which not only blocks all UV radiation but spills slightly into the visible spectrum resulting in an overall warm tint to the photograph.
