aoLED | Optogenetics LEDs

aoLED integrates into a single device a linear and stable LED driver and fibre-coupled LED, suitable for optogenetics and calcium imaging. The device is a compact and powerful all-in-one stimulus tool able to generate a stable, long lasting and high intensity light signal through a high NA 200um core fibre. The custom designed electronics allow high-precision analog signal modulation (up to 10 kHz), opening the possibility of experimenting with new light stimulus temporal shapes, such as ramps, sinusoids or modulated signals, as well as fast digital modulations to generate sharp and stable stimuli.

aoLED is equipped with two parallel feedback systems which monitor the current absorbed by the LED and the light actually emitted by the LED. In doing so, aoLED can detect and compensate for thermal and age induced variations in output to ensure a highly stable performance across individual stimuli, between subsequent stimuli and across experiments. Both measurements are available as analogue signal outputs from aoLED and allow full monitoring of the experimental conditions.

CyNexo can supply an Arduino-based controller with its independent software or as an Open Ephys plug-in. Alternatively, aoLED can also be controlled via a normal analog signal (0-5V) giving you all the flexibility you might need to adapt it to your specific experimental environment.

Available custom variants:

– Skull implantable led version

– In vitro version for direct illumination of biological well plates
