With this photodiode kit we provide you an easy to use and efficient tool for a variety of applications. Since the gain of the integrated amplifier can be modified, it is straightforward to customize it to suit your needs.
For maximum flexibility the photodiode can either be powered by an external power source via the DC jack or using coin cell batteries. To increase battery life, if present, the external power source is automatically selected. Due to the wide range of accepted supply voltages, different output voltage swings are possible.
The kit comes with SMD parts assembled. So only the through-hole components need to be soldered by the user. Using the included mounting bracket, the photodiode can be mounted to a post with the connectors either facing upwards or sidewards.
An adapter with an internal SM1 thread, that allows mounting of filters or other optical elements right in front of the photodiode, is available as an accessory.
