Description
Photodiodes are photodetectors that convert incident light into a current or voltage dependent on their configuration. They have replaced photomultiplier tubes for most applications. For fluorometric measurements that do not require spectral data, a single photodiode with suitable filters can be used. Due to their larger detection area, they are more sensitive than photodiode arrays.
