||Actually, this block visible, passes UV!
|I wanted a UV pass filter for photography for years. Typically these are hundreds of dollars. I saw these and could not resist buying several. You have to make your own mount and theyre a little undersized for most SLR lenses, but most digital cameras can detect UV and you can get a useful UV image thru these filters.|

|Overall blocks all UV from getting in, which is great.|
