LZ1-x0UB0R VIOLET LED Emitters LED Engin LZ1-x0UB0R VIOLET LED Emitters are designed to provide superior radiometric power in a wavelength range of 385nm to 420nm. These VIOLET LED emitters offer low thermal resistance while providing an electrically neutral thermal path. The LZ1-x0UB0R VIOLET LED Emitters feature high radiant flux density with an exceptional thermal and optical performance. These emitters are available in a small footprint of 4.4 mm x 4.4 mm and a surface-mounted ceramic package with an integrated glass lens, which provides excellent optical power density.
