Avalanche Photodiodes

Excelitas offers Avalanche Photodiodes (APDs) on both Silicon (Si) and InGaAs materials. Si APDs cover the spectral range of 400 nm to 1100 nm and the InGaAs APDs cover 950 nm to 1550 nm. An Avalanche Photodiode (APD) provides higher sensitivity than a standard photodiode and is for extreme low-level light (LLL) detection and photon counting.

APDS而不是PIN光电探测器的使用将导致许多应用中的灵敏度提高。必威平台怎么样通常，APDS在放大器噪声高的应用中是有用的，例如，远高于PI必威平台怎么样N光电探测器中的噪声。
