OptoFlash

LED-based flash lamp for short-duration, high-intensity light pulses

  • User-defined flash intensity
  • Excellently-suited for optogenetics and flash photolysis applications

Like other products in the OptoLED family, the OptoFlash uses LED heads, fibers and microscope coupling designs. However, the OptoFlash has been optimized for short-term intense illumination. This makes it particularly suitable for the photoactivation of “caged” neurotransmitter or other compounds, and for the  application of channel rhodopsin activation.
