B+W 010 UV blocking test

B+W 010 UV blocking test
The B+W 010 UV Haze filter blocks some UV light, you can see the bottom of the flash through the filter, while the part of the flash above the filter is a lot brighter. But the fact that the flash can be seen through the filter at all shows that the filter is not blocking all UV light, just reducing the intensity.

This result agrees with the transmission graph for the filter posted in the photo.net article Filters - UV or not UV?.
