Aspects of the invention include methods for adjusting the sensitivity of a photodiode in a light detection system. A method according to certain embodiments includes detecting light with a light detection system having a photodiode and an amplifier; determining the responsivity of the photodiode under various optical wavelengths; and adjusting one or more parameters of the amplifier for the responsivity of the photodiode at the plurality of optical wavelengths. Methods for implementing the subject, systems (e.g., particle analyzers) having a light source and a light detection system including a photodiode and an amplifier are also described. The invention also provides a non-transitory computer readable storage medium. 本发明的方面包括用于调整光检测系统中光电二极管的灵敏度的方法。根据某些实施例的方法包括用具有光电二极管和放大器的光检测系统检测光；确定所述光电二极管在多种光波长下的响应度；以及针对所述光电二极管在所述多种光波长下的所述响应度，调整所述放大器的一个或更多个参数。本发明还描述了用于实施标的方法、具有光源和光检测系统的系统(例如，颗粒分析仪)，所述光检测系统包括光电二极管和放大器。本发明还提供了非暂时性计算机可读存储介质。
