UV Sunscreen

Out of curiosity, we decided to takes a series of UV pictures using Edmund Optics +-/10nm bandwidth filters using our Llewellyn Optics fused silica M12 lens, debayered 8MP USB camera with Sony IMX 179 sensor with no cover glass.  We used archival, acid-free paper that contained no fluorescent brighteners.  Pictures were taken in sunlight at around 1PM on a  sunny day in August.
