One of the earliest applications of UV LEDs was in fluorescence microscopy starting in the late 1990s. While initial UV LED outputs were low, they provided significant advantages over mercury lamps such as longer lifetime, compact size, and precise control. This allowed for new fluorescence microscope designs focused on portability and cost reduction. As UV LED power output steadily i... https://hallbook.com.br/blogs/433144/Understanding-the-Technology-Behind-UV-LEDs
