Like other products in the OptoLED family, the OptoFlash is LED-based with coupling options for most microscopes. The option to launch the OptoFlash into a fiber optic with the diameter ranging from 100um to 1mm is also available. The OptoFlash is unique in that it has been optimized for short-term intense illumination. This makes it particularly suitable for the photoactivation of “caged” neurotransmitters or other compounds, and for the application of channel rhodopsin activation.
