MaxMile Technologies 光致发光测试仪

EpiEL-700 is optimized for rapid electroluminescence (EL) evaluation for LED epiwafers with optically transparent substrates, such as nitride-based LED  on sapphire substrate. It has all functions of EpiEL-100 with additional capability for simulating different light extraction approaches. EpiEL-700 can also be used to investigate optical non-uniformity of material structures which leads to different emission intensity on both sides of the epiwafers.

EpiEL-700是为带有光透明衬底的LED外延片快速电致发光评估设计的，例如在蓝宝石衬底上的氮化物基LED。它有EpiEL-100的所有功能，另外附加模拟不同的光提取方法的功能。 EpiEL-700也可用于研究材料结构的光学非均匀性，这种非均匀性导致外延片两侧产生不同的发射强度。
