MEMOCVD™
The
UVTOP
is a series of ultraviolet and deep ultraviolet hermetically packaged
light emitting diodes with peak emission wavelengths in the range of 250 nm to
365 nm. A
MEMOCVD™-
grown AlGaN/GaN LED chip/chip array is
encapsulated in a metal-glass TO-39 package with UV-transparent optical window.
