Applications/Examples of results
● Skin Treatment Ultraviolet treatment for vitiligo and psoriasis typically involves PUVA therapy using UV-A or 310nm UV-B narrowband lamp light sources in combination with oral medications. Recently, there has been progress in using LED light sources. LEDs can miniaturize the light source, allowing for targeted ultraviolet light irradiation only on the necessary areas, making them ideal for targeted treatment devices. There is a high demand for alternatives to UV-B narrowband lamps at 311nm and excimer lamps at 308nm, and DoUVLEDs can accommodate both 311nm and 308nm. ● Resin Curing Ultraviolet light sources act on photoinitiators to promote the curing of the resin's main components, monomers, and oligomers. UV curing is ideal for applications where heat history should be avoided, such as bonding optical components, as it does not use heat. Additionally, since it does not involve solvents, there is no generation of harmful gases. ● Sensing Various detection and sensing applications utilize the unique ultraviolet absorption characteristics of substances, including transmission-type sensors and fluorescence or phosphorescence analysis devices that measure the excitation light generated by ultraviolet irradiation.
