I bought Plexbright rotary mounted LED’s from Plexon, and have used a collaborator’s Prizmatix LED. Both were blue LED’s and worked fine to stimulate ChR2 in vivo.
I’m interested to know what optogenetics equipment anyone else has bought, and was it any good?
I’m particularly interested to know about other colour LED’s, as I don’t think the ones from Plexon and Prizmatix are bright enough.
