Precision, wide-bandwidth current source with optional optical feedback mode for driving high-power LEDs and laser diodes. Good for sneaking optogenetic stimuli between fast things (e.g. galvo flyback on a 2P system). Good for really controlling the amount of light you deliver during 1P imaging or optogenetic stimulation.
If you have questions or comments, please come talk on the open-ephys slack in the #cyclops channel.
