一、 尺寸；Size
二、描述；Description
L5IR
所以這些發(fā)射二極管是理想的作為標(biāo)準(zhǔn)發(fā)射器件的高性能產(chǎn)品。
L5IR
In comparison with the standard GaAs on GaAlAs technology these emitters achieve more than 100 % radiant power improvement at a similar wavelength. The forward voltages at low current and at high pulse current roughly correspond to the low values of the standard technology.
Therefore these emitters are ideally suitable as high performance replacements of standard emitters.
