General

UV LEDs emit invisible UV light at the wavelength less than 380nm. While colored LEDs and infrared LEDs are already introduced in the market, it was believed that the development of shorter wavelength UV LEDs was impossible as the emission efficiency from semiconductors at the shorter wavelength is easy to get deteriorated.
However we succeeded in the development of the world first UVLED at 350nm wavelength with high efficiency in 2000 and continuously introduced UV LEDs at the wavelength of 375nm, 370nm and 365nm to the market in the following years. We make and sell epitaxial wafers, UV LED chips and UV LED lamps.
