IMPORTANT: This is not a pure UV filter!
The ZWB3 black ultraviolet glass can distribute some of the visible light in blue-violet light. Its main function is to remove visible stray light from a 254nm UV lamp. As it is used in LF natural light filtering or full spectrum photography, the visible blue-violet light can lead to obvious infection. This is not a quality problem. Please pay attention before purchasing.
