LED UV

UV-LEDs require unique and delicate production process. Nichia places strict controls from wafer manufacturing to final inspection. For more than 20 years, Nichia UV-LEDs have been chosen by demanding customers that require rigorous quality such as high precision curing, ink curing (printing), bill checker etc.
